How that happens though is not quite so simple. Well it used to be back in the days when cars were called horseless carriages, but nowadays, not so much. The steering knuckles system is where the axles themselves, which are mounted on a knuckles, out and away from the go kart, and they actually rotate around these pivots, and cause the wheels to turn by using of hydraulic single acting cylinder.\r\nAnd also using Pascal\u2019s law by moving of the hydraulic single acting cylinder. In our project we had made the system so simple by including the worm gear attachments which powers the rotation given through the steering wheel. Along with the worm wheel setup a potentiometer is included for boosting the power of rotation obtained from the steering wheel for the rotation of D.C motor so it powers worm wheel arrangement to activate at normal speed for performing the activation of the wheels for controlling of vehicle.\r\n\r\nRead More:\u00a090 DEGREE TURNING STEERING MECHANISM Automobile Mechanical Project\r\n\r\nINTRODUCTION:\r\nWheel Steering System is employed in vehicles to achieve better maneuverability at high speeds, reducing the turning circle radius of the car and to reduce the driver\u2019s steering effort. In most active 4-wheel steering system, the guiding computer or electronic equipment play a major role, in our project we have tried to keep the mechanism as much mechanical as possible which can be easy to manufacturing and maintenance.\r\nThis project focuses on a mechanically feasible &amp; innovative design involving a double rack and pinion system for rear wheels enclosed within a casing, connected to the steering column by a combination of a bevel gear assembly &amp; telescopic shaft. The movement of the rear wheels is done by the movement of the rear pinions which in turn move the newly designed spindle to achieve the required movement of the rear wheels.\r\n\r\n2D LAYOUT OF ACTIVE STEERING SYSTEM:\r\n\r\ndesign and fabrication of active steering system\r\n\r\nWorking principle:\r\nThe working system consist of steering wheel arrangement which is connected to an axle by means of worm and wheel attachments the axle is linked with the wheels by means of several linkages, so the activation of the steering wheel functions the wheel to move from left to right based up the driver convenience. In order to increase its efficiency, the D.C motor is coupled with an arrangement which is powered by means of potentiometer disturbances caused by the activation of the steering wheel when the wheel gets tilted at certain angle then the disturbances is transferred to the potentiometer which boosts the rotation and tends to rotate the D.C\r\nmotor at the required speed for the activation of worm wheel arrangement. So handling of this system is easy and efficient when compared to the existing one.\r\n\r\nRead More:\u00a0Front Wheel Steering System with Movable Headlights Report Download\r\n\r\nADVANTAGES:\r\n\r\n \tThe vehicle\u2019s cornering behavior becomes more stable and controllable at high speeds as well as on wet or slippery road surfaces.\r\n \tThe vehicle\u2019s response to steering input becomes quicker and more precise throughout the vehicle\u2019s entire speed range.\r\n \tThe vehicle\u2019s straight-line stability at high speeds is improved.\r\n \tNegative effects of road irregularities and crosswinds on the vehicle\u2019s stability are minimized.\r\n \tThe vehicle is less likely to go into a spin even in situations in which the driver must make a sudden and relatively large change of direction.\r\n \tBy steering the rear wheels in the direction opposite the front wheels at low speeds, the vehicle\u2019s turning circle radius is greatly reduced. Therefore, vehicle manufacturing on narrow roads and during parking becomes easier.\r\n\r\nAPPLICATIONS:\r\n\r\n \t\u00a0For automobile application especially for four wheelers.","headline":"Design and Fabrication of Active steering System","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-06-20","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/06\/design-and-fabrication-of-active-steering-system-300x114.jpg","height":114,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/7-stages-of-new-product-development-process/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/06/7-stages-of-new-product-development-process-300x255.jpg')"></div><span class="sr-only">link to 7 stages of new product development process</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/7-stages-of-new-product-development-process/">7 stages of new product development process</a></p></header><div class="excerpt"><p>7 stages of new product development process

Idea generation (Idea Formulation)\r\n\r\n\r\n2. Screening of ideas (Evaluation)\r\n\r\n\r\n3. Concept Testing\r\n\r\n4. Business analysis\r\n\r\n5. Product development\r\n\r\n6. Test marketing\r\n\r\n7. Commercialization (Market Introduction)\r\n\r\n 7 stages of new product development process\r\n1. Idea Generation:\r\nThe focus in this first stage is on searching for new product ideas. Few ideas generated at this stage are good enough to be commercially successful. New product ideas come from a variety of sources. An important source of new product ideas is customers. Fundamentally, customer needs and wants seem to be the most fertile and logical place to start looking for new product ideas. This is equally important for both consumers and industrial customers.\r\n\r\nProduct planning starts with the creation of product ideas. The continuous search for new scientific knowledge provides the clues for meaningful idea formation.\r\n\r\nDrucker suggested that the sources can broadly be divided into:\r\n\r\n(a) Internal Source (within the company) and\r\n\r\n(b) External Sources (outside the company)\r\n2. Screening the Ideas: (Evaluation):\r\nIt means critical evaluation of product ideas generated. After collecting the product ideas, the next stage is screening of these ideas. The main object of screening is to abandon further consideration of those ideas which are inconsistent with the product policy of the firm. The product ideas are expected to be favourable and will give room for consumer satisfaction, profitability, a good market share, firm\u2019s image.\r\n\r\n\r\nAll the ideas cannot be accepted, because certain product plans need huge amount of investments, for certain plans raw materials may not be available, certain plans may not be practicable. Many of the ideas are rejected on account of many reasons and thus eliminate unsuitable ideas. Only promising and profitable ideas are picked up for further investigation.\r\n\r\n\r\nAnswers are sought to questions like:\r\n\r\n1. Does the product meet a genuine need?\r\n\r\n2. Is it an improvement over the existing product?\r\n\r\n3. Is it close to our current lines of business?\r\n\r\n4. Does it a totally new line of business?\r\n\r\n5. Will it offer customers a superior value?\r\n\r\n6. Will the new product bring in expected ROI?\r\n\r\n7. Does the market accept the new product?\r\n3. Concept Testing:\r\nAfter the new product idea passes the screening stage, it is subjected to \u2018concept testing\u2019. Concept testing is different from test marketing, which takes place at a later stage. What is tested at this stage is the \u2018product concept\u2019 itself-whether the prospective consumers understand the product idea, whether they are receptive towards the idea, whether they actually need such a product and whether they will try out such a product if it is made available to them.\r\n\r\nIn fact, in addition to the specific advantage of getting the consumers\u2019 response to the product idea, this exercise incidentally helps the company to bring the product concept into clearer focus. Concept testing helps the company to choose the best among the alternative product concepts. Consumers are called upon to offer their comments on the precise written description of the product concept, viz, the attributes and expected benefits.\r\n4. Business Analysis (Market Analysis):\r\nThis stage is of special importance in the new product development process, because several vital decisions regarding the project are taken based on the analysis done at this stage. Estimates of sales, costs and profits are important components of business analysis and forecasts of market penetration and market potential are essential.\r\n\r\nMore precise estimates of environmental and competitive changes that may influence the product\u2019s life cycle or its replacement or repeat sales are also needed to develop and launch a product? A complete cost appraisal is necessary besides judging the profitability of the project.\r\n\r\nMarket analysis involves a projection of future demand, financial commitment and return. Financial specialists analyze the situation by applying break-even analysis, risk analysis. Business analysis will prove the economic prospects of the new product.\r\n5. Product Development:\r\nThe idea on paper is converted into product. The product is shaped corresponding to the needs and desire of the buyers. Product development is the introduction of new products in, the present markets. New or improved products are offered by the firm to the market so as to give better satisfaction to the present customers. Laboratory tests technical evaluations are made strictly.\r\n6. Test Marketing:\r\nBy test marketing, we mean, what is likely to happen, by trial and error method when a product is introduced commercially into the market. These tests are planned and conducted in selected geographical areas, by marketing the new products. The reactions of consumers are watched.\r\n\r\nIt facilitates to uncover the product fault, if any, which might have escaped the attention in the development stage. By this, future difficulties and problems are removed. This type of pre-testing is essential for a product before it is mass produced and marketed. Sometimes, at this stage, management may take decision to accept or reject the idea of marketing products.\r\n\r\nDesigning the programme for test marketing involves making a number of decisions:\r\n\r\n1. Where and in how many markets should test be carried out?\r\n\r\n2. What should be the duration of test marketing?\r\n\r\n3. What to test?\r\n\r\n4. What criteria should be used to determine success or otherwise?\r\n7. Commercialization (Market Introduction):\r\nThis is the final stage of product planning. At this stage, production starts, marketing programme begins to operate and products flow to the market for sale. It has to compete with the existing products to secure maximum share in the market-sales and profits. When a product is born, it enters into the markets; and like human beings, has a life span-product life cycle.\r\n\r\nIn launching a new product, the company must make four decisions:\r\n\r\n1. When should the product to be launched?\r\n\r\na. Right time.\r\n\r\n2. Where should it be launched?\r\n\r\ni. a single locality\r\n\r\nii. a region or\r\n\r\niii. national market.\r\n\r\n3. Which groups should be targeted?\r\n\r\na. Existing customers.\r\n\r\n4. How should it be launched?\r\n\r\ni. Develop an action plan for introducing the new product into the rollout markets.\r\n\r\nConsider the following before launching a new product:\r\n\r\n1. Effective market research\r\n\r\n2. Ensure product quality\r\n\r\n3. Differentiation of product\r\n\r\n4. Identification of consumer needs\r\n\r\n5. Effective promotion\r\n\r\n6. Proper distribution system\r\n\r\n7. Correct pricing strategy\r\n\r\n8. Knowledge of local needs\r\n\r\n9. Choose correct time\r\n\r\n10. Strength of sales force.\r\n\r\nFactors that hinder the new product development:\r\n\r\n1. Shortage of ideas\r\n\r\n2. Shorter PLC\r\n\r\n3. Higher expenditure\r\n\r\n4. Fragmented markets\r\n\r\n5. Inappropriate incentives\u00a0\r\n\r\n6. High gestation period\r\n\r\n7.

The programs produce a computer file that is interpreted to extract the commands needed to operate a\r\nparticular machine via a post processor, and then loaded into the CNC machines for production. Since any particular component might require the use of a number of different tools \u2013 drills, saws, etc., modern machines often combine multiple tools into a single \"cell\". In other\u00a0installations, a number of different machines are used with an external controller and human or robotic operators that move the component from machine to machine. In either case, the series of steps needed to produce any part is highly automated and produces a part that closely matches the original CAD design.\r\n\r\nWith the on-going development of technology and economy, new industrial requirements such as high precision, good quality, high production rates and low production costs are increasingly demanded. Most of such requirements, including dimensional accuracy,\r\nconformance to tolerances of finished products and production rate can be met with better\u00a0machine tools. With the help of CNC technology, machine tools today are not limited to human capabilities but are able to make ultra-precision products down to Nano scales in a much faster manner. The traditional design philosophy of machine tools is multi-functionality and highest precision possible. However, with the dramatic increase of industry varieties and the growing demand of miniature products, these general purpose machine tools are not efficient, either in terms of machine time or cost, in manufacturing products with special sizes and precision requirements\r\n\r\nThere are several advantages of using small machines to produce small sized objects. With a smaller machine size, space is saved. The energy required to operate the machine is reduced as well. It now requires less material and components to make the machine, hence\u00a0bringing down the cost greatly. The weight of moving component also comes down so that during operation, the vibration and noise, as well as pollution to the environment, are markedly reduced. As the machine becomes denser and lighter, it becomes more portable. The layout of\u00a0the manufacturing plant can be more flexible. The productivity and manufacturing speed also increases due to possible faster operation.\r\n\r\nRead More:\u00a0Basic Of Milling -Up Milling and Down Milling\r\n\r\nObjective:\r\nThe idea behind fabrication of low cost CNC Milling Machine is to full fill the demand of CNC machines from small scale to large scale industries with optimized low cost. A major new development in computer technology is the availability of low-cost open source hardware, such as the Arduino microcontroller. An advantage of open source hardware is that a wide variety of ready-to-use software is available for them on the Web; therefore the prototyping and development times are drastically reduced. Moreover, a wide range of low-cost interfaces and accessories such as Arduino shields are also available. However, for the development of low-cost models of CNC machines, such tools may be quite adequate from the viewpoint of machine control. In this project, the development of a prototype 3-axis CNC Milling Machine using Arduino-based control system is presented with the following specification.\r\n\u2022 Low cost\r\n\u2022 Easily operable\r\n\u2022 Easy interface\r\n\u2022 Flexible\r\n\u2022 Low power consumption\r\n\r\nhow to make cnc milling machine - circuit Diagram\r\n\r\nMethodology:\r\nThis system can be divided in to three modules.\r\n\u2022 Mechanical system\r\n\u2022 Electrical system\r\n\u2022 Software system\r\n\r\nMechanical system gets necessary control signals from electronics system which ultimately results in desired actuation of motors. Electronics system gets command or a set of commands from software system and generates controls for mechanical system.\r\n\r\nMechanical System\r\nThe mechanical system is assembled in such a way that the 3-axis movement is achieved by using the linear bearings and guide rods. Stepper motors are mounted to the each axis which is the source of motion acted according to the control signal generated from the electronics\u00a0circuit. Each stepper motor is coupled to the screw rod which carries nut with the help of coupling bush. This screw rod and nut arrangement is responsible for converting the rotational motion of the stepper motor to linear motion. The linear motion of each axis is carried away\u00a0smoothly by the linear bearing and guide rod assembly connected to the each axis which is capable of load carriers and allows linear motion in each axis.The controlled motion in each axis is achieved directly by controlling the rotation of the stepper motor. The speed of the motion in each axis can also be controlled by direct control of the speed of the stepper motor by giving required control signals. Thus the tool path of the spindle fixed to the end effector is controlled in each axis for smooth carving or cutting action of work piece.\r\n\r\nElectrical System\r\nElectronics system comprises of:\r\n\u2022 Power supply\r\n\u2022 Microcontroller board\r\n\u2022 Stepper motor driver board\r\nPower Supply\r\nPower supply is heart of the CNC system which converts the AC voltage to DC voltage and supplies required voltages to the corresponding devices. Microcontroller board operates at 5v supply whereas the stepper motor board operates at 12v.\r\n\r\nMicrocontroller Board\r\nATMEGA 328p Arduino based microcontroller development board is chosen here to control the motion of the system. It acts as brain of the CNC system which receives the commands from the software system from computer connected through the USB serial port.\r\nArduino development board is flashed with the GCODE interpreter code which was written in the C language, which is responsible to generate the control signal for corresponding command signal from the computer system to the stepper motors which directly controls the motion of the tool path. The command from computer or software system is received and converts them to the actual electronic signals to the Stepper Motor Driver Board.\r\n\r\nStepper Motor Driver Board\r\nPololu A4988, micro-stepping drive designed for smooth and quiet operation is chosen to drive the NEMA 17 stepper motor. Stepper motor Driver Board receives the control signal from the microcontroller board to the terminals PULSE and DIR which generates the corresponding\u00a0digital pulse signals for stepper motor to control the rotation of the motor.\r\n\r\nSoftware System\r\nThe software tool chain of CNC-based manufacturing is represented in the fig 1. The part to be machined is designed in computer-aided design (CAD) software, whose output is a drawing in one of many acceptable formats most preferable format is .stl format. This drawing is then fed to the computer-aided manufacturing (CAM) software, whose output is the machine readable code used for numerical control of the machine. Since implementation of the G code is machine dependent, it is necessary to test out different choices for an open source G code interpreter for the Arduino, so that the correct motions are obtained for the machine axes through the stepper motor driver. We have used grbl, an open source G-code interpreter or milling controller for the Arduino development board.","headline":"Design and Manufacturing of CNC Milling for Small scale Industries","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-06-19","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/06\/how-to-make-cnc-milling-machine-circuit-Diagram-300x182.jpg","height":182,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/automatically-timed-kinematic-transport-system-mechanical-project/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/06/Automatically-Timed-Kinematic-Transport-System-Mechanical-Project-300x154.jpg')"></div><span class="sr-only">link to Automatically Timed Kinematic Transport System &#8211; Mechanical Project</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/automatically-timed-kinematic-transport-system-mechanical-project/">Automatically Timed Kinematic Transport System &#8211; Mechanical Project</a></p></header><div class="excerpt"><p>Automatically Timed Kinematic Transport System - Mechanical Project

In this process, the movement of job from one station to another is accomplished by a belt conveyor system. This system uses an electric drive which is continuous. So the operator does not get sufficient time to complete the operation. Thus the jobs are usually picked and placed on to the work station and the job is processed. This is a tiring and a time consuming job. Also for heavy materials, a separate setup is required for the pick and place operation.\r\nThis project proposes the model of a timed transport mechanism. This system uses kinematic linkages for timing the transportation. It uses a four bar mechanism, that follows a coupler curve. It has a greater advantage than the existing system of transport of work piece in a factory.\r\n\r\nINTRODUCTION\r\nMaterial-handling equipment is equipment that relate to the movement, storage, control and protection of materials, goods and products\r\nthroughout the process of manufacturing, distribution, consumption and disposal. Material handling equipment is the mechanical equipment involved in the complete system.\r\n\r\nMaterial handling equipment is generally separated into four main categories: storage and handling equipment, engineered systems, industrial trucks, and bulk material handling. Material handling equipment is used to increase output, control costs, and\r\nmaximize productivity. There are several ways to determine if the materialhandling equipment is achieving peak efficiency. These include capturing all relevant data related to the warehouse\u2019s operation, measuring how many times an item is \u201ctouched\u201d from the time it is ordered until it leaves the building, making sure you are using the proper picking technology, and keeping system downtime to\r\na minimum. A special analytical data-set known as Stock-keeping units (SKUs) has been devised to aid analysis of materials handling, which is obviously less efficient when a material asset is handled any more than a minimally necessary\r\nnumber of times.\r\n\r\nWORKING PRINCIPLE:\r\n\r\n \tThis system uses a four bar mechanism, that follows a coupler curve.\r\n \tIt has a greater advantage than the existing system of transport of work piece in a factory.\r\n \tThe materials are transferred from one work station to another at a specific time interval, which is based on the movement of the linkages.\r\n \tIn a continuous assembly factory, there is a need to transfer materials or on process jobs form one working station to the other. In this process, the movement of job from one station to another is accomplished by a belt conveyor system.\r\nSystem uses an electric drive which is continuous. So the operator does not get sufficient time to complete the operation.\r\n \tThus the jobs are usually picked and placed on to the work station and the job is processed. This is a tiring and a time consuming job. Also for heavy materials, a separate setup is required for the pick and place operation. This project proposes the model of at imbed transport mechanism.\r\n \tThis system uses kinematic linkages for timing the transportation. It uses a four bar mechanism, that follows a\r\ncoupler curve. It has a greater advantage than the existing system of transport of work piece in a factory.\r\n\r\nBLOCK DIAGRAM:\r\nA four-bar linkage, also called a four-bar, is the simplest movable closed chain linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage.\r\nIf the linkage has four hinged joints with axes angled to intersect in a single point, then the links move on concentric spheres and the assembly is called a spherical four-bar linkage.\r\n\r\nLAYOUT OF THE SYSTEM\r\n\r\nAutomatically Timed Kinematic Transport System - Mechanical Project\r\n\r\nADVANTAGES:\r\n\r\n \tElectronic control is not required\r\n \tThe time required for assembly is greatly reduced.\r\n \tThe extra work needed to transfer the work piece from the main transport system to a work station is eliminated.\r\n \tThe efficiency of the system is higher as number of friction parts is lesser.\r\n \tThe timing of the system can be easily varied based on the application.\r\n \tIt is an economic design.\r\n\r\nAPPLICATIONS:\r\n\r\n\u2022 Job feeding systems\r\n\u2022 Continuous assembly plant\r\n\u2022 Packaging industries","headline":"Automatically Timed Kinematic Transport System &#8211; Mechanical Project","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-06-18","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/06\/Automatically-Timed-Kinematic-Transport-System-Mechanical-Project-300x154.jpg","height":154,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/core-subjects-mechanical-engineering/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/06/core-subject-mechanical-drawing-300x168.jpg')"></div><span class="sr-only">link to What are the Core Subjects for Mechanical Engineers ?</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/core-subjects-mechanical-engineering/">What are the Core Subjects for Mechanical Engineers ?</a></p></header><div class="excerpt"><p>What are the Core Subjects for Mechanical Engineers ?

This is new modification in engineering field it simply structure and using any industries.\r\n\r\nWORKING PRINCIPLE:\r\n\r\nThis is system totally operated the hand lever mechanism, going to future model it is operated servo motor and any other motor system, which is used for safety lock system having ratchet and pinion gear mechanism and it is connect the rope by on pulley guide, this hole component connects the hand lever shaft, when you need the weight lifting system simply drive the hand lever and also drive pulley.\r\n\r\nsafety lift mechanism\r\n\r\nThe pulley connects the pinion and also connect the weight it is going up step by step by in rack gear based.\r\nAny one of the condition you have an unbalancing and leave the hand lever condition that system totally stop and lock on ratchet and pinion system.\r\n\r\nADVANTAGE:\r\n\r\n \tEasiest method of any heavy weight lifting.\r\n \tMost applicable for safety system in heavy load lifting condition.\r\n \tIt is used for small and large scale industries.\r\n \tCost is low on fabricate system.","headline":"Design and Fabrication Of Safety lift Mechanism","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-06-17","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/06\/safety-lift-mechanism-300x144.jpg","height":144,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <nav class="pagination-wrapper" aria-label="article pagination"> <a class="prev page-numbers" href="?page_num=181">&laquo; PREV</a> <a class="page-numbers" href="?page_num=1"><span class="screen-reader-text">Page </span>1</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=180"><span class="screen-reader-text">Page </span>180</a> <a class="page-numbers" href="?page_num=181"><span class="screen-reader-text">Page </span>181</a> <span aria-current="page" class="page-numbers current"><span class="screen-reader-text">Page </span>182</span> <a class="page-numbers" href="?page_num=183"><span class="screen-reader-text">Page </span>183</a> <a class="page-numbers" href="?page_num=184"><span class="screen-reader-text">Page </span>184</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=338"><span class="screen-reader-text">Page </span>338</a> <a class="next page-numbers" href="?page_num=183">NEXT &raquo;</a></nav></section></main><aside id="secondary" class="widget-area"><div class="about-wrapper"><h2 class="widget-title" style="background: #d693c6; color: #ff392e">About Us</h2><div class="about-image" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2020/03/Sachin-Thorat-300x300-min.png')"></div><p class="about-copy">LearnMech.Com is a Mechanical Project-oriented platform run by Sachin Thorat who is a B-Tech Graduate in Mechanical Engineering.
