Being one is not easy since the hardship starts in college. The expectations are high once in the workplace. If you are interested in this field, you might find it helpful to read some insight on mechanical engineering work. Before one becomes a mechanical engineer, one has to undergo a long process. But once you are qualified you\u2019ll surely reap the fruits of your labour. Mechanical engineers are looked up to these days, and there are a string of opportunities that awaits them in the industry.\r\n\r\nmechanical engineering Rocks\r\n\r\n\r\n\r\n\r\nWhat it takes to be a Mechanical Engineer?\r\n\r\nPrimarily, mechanical engineers are expected to be well-versed in multiple disciplines in science. This may include geometry, trigonometry, calculus, algebra, chemistry, physics and biology. The combination of these specific sciences is important to come up with innovative plans and creations for the public\u2019s welfare.\u00a0\r\n\r\nA normal working week of a mechanical engineer is at least 40 hours per week. They are normally faced with heavy workloads and tight deadlines. They can be assigned in the field or in the office depending on the needs of their current project. Mechanical engineers are considered genuine innovators as they enjoy solving highly complex problems.\r\n\r\nTo qualify for this position, you need to be a graduate of a mechanical engineering course. A test may be required to be taken as well. Interestingly, the demand for mechanical engineers is projected to increase in the coming years. Top engineers can earn up to $90,000 annually which really is a huge amount.\r\n\r\nTips to Help You Pass the Mechanical Engineering Certification\r\n\r\nFor you to become a genuine and sought-after mechanical engineer, you might need to pass a certification to demonstrate greater prospects for yourself and your employer. Since this field requires critical skills and intensive hands-on training, the employers initially assess if you really understand the field that you are in. There should also be a definite yardstick to check if the student has learnt things that are important in the field such as mathematics, lab training and computer training. Certifications are often a requirement in most engineering posts. Below are some tips to help pass the mechanical engineer certification.\r\n\r\nReview your books and handouts in college\r\n\r\nThere is no need to memorise everything. You just need to refresh your memory on the theories and concepts that you discussed in line with your course. Reading them frequently helps you understand the topics more easily. Do not put too much pressure on yourself as this doesn\u2019t help.\r\n\r\nAsk People Who Have Already Taken The Exam\r\n\r\nYou don\u2019t need to ask them the actual questions asked as they may not be able or willing to share those, rather ask about the style and structure of the exam. You may ask them about the particular subjects that the mechanical engineering exam focuses on. These are basic tips to pass the mechanical engineer certification. You would not find it very hard if you truly understand the field you are in. Basically, this certification serves as an affirmation that you are ready to practise the profession. There should always be a set of standards for practicing mechanical engineering\u2014or other engineering fields\u2013as they have great roles in the development of the society as a whole. Complexity of a mechanical engineer\u2019s workload often discourages some people to pursue this career.

It is capable of machining\u00a0a horizontal, vertical or inclined flat surface. Shaper and planer employ single-point cutting tools which are essentially\u00a0similar to single-point cutting tools used on lathe. In both these machine tools, the cutting tool is subjected\u00a0to interrupted cuts, the tools cuts in forward direction and is idle in the return direction.\r\n\r\n\r\nShaper consists of a hollow machine bed made of cast iron which rests on the ground. Inside the\u00a0hollow portion the machine drive mechanism is housed. This mechanism is called slotted lever quick\u00a0return mechanism and it drives a horizontal ram which reciprocates in the guide ways provided on the\u00a0top surface of the machine frame. In the front face of the ram, a tool post is fitted. This is a very special\u00a0kind of tool post. It carries a slide which can be operated by a hand wheel and the entire tool post can be\u00a0lowered or raised. Besides, the tool slide can be swivelled in a vertical plane and its inclination to the\u00a0vertical (amount of swivelling) can be read off on a scale marked in degrees. The tool is inclined, when\u00a0an inclined surface has to be machined.\r\n\r\n\r\n\r\n Pneumatic Shaping Machine Mechanical Project\r\n\r\n\r\nAdvantage\u00a0\r\n1) Low cost machine\u00a0\r\n2) Maintenance free\r\n\r\nDisadvantage\u00a0\r\n1) Stability is low compare to hydraulic\u00a0\r\n2) Constant pressure is needed for operated the machine\r\n\r\n\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nPneumatic or Air operated projects\r\nMachine Shop Projects List , Abstract\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )","headline":"PNEUMATIC QUICK RETURN MECHANISM FOR SHAPING MACHINE","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2016-04-11","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2016\/04\/PNEUMATICQUICKRETURNMECHANISMBYSHAPINGMACHINE-300x180.png","height":180,"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/flywheel-based-battery-charger/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2016/04/FlywheelBasedBatteryCharger-300x164.jpg')"></div><span class="sr-only">link to Flywheel Based Battery Charger Mechanical Project</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/flywheel-based-battery-charger/">Flywheel Based Battery Charger Mechanical Project</a></p></header><div class="excerpt"><p>Flywheel Based Battery Charger Mechanical Project

This flywheel is made to run by human power, which is transmitted to the same using paddle, sprocket, chain and free wheel mechanism.\u00a0\r\n \tThe mechanical power from this flywheel is then transmitted to the electricity generator using transmission that multiplicities the speed of flywheel and then transmit it to the generator unit.\u00a0\r\n \tThe mechanical power from the flywheel thus gets converted into electric power that is there after stored in a secondary battery using a charging circuit that has various functionalities associated with it like wise overcharging protection, low discharge cut off, high voltage cut off, current back flow proofing etc.\u00a0\r\n \tThe whole assembly is put together in a space frame made up of iron. As far as possible the frame is made portable and easy to carry.\r\nThe capacity of the project can be varied from 1.5 volt battery charging to 12 volt battery charging. The size of the project work varies as that of capacity.\r\n \tThis project has very potential to considering commercial point of view. As load shedding is major on going issue in remote, rural as well as urban area. This device can perform well for agricultural as home use. In urban area this device can also perform the work of exercising machine as well as can also be used for back to electricity.\u00a0\r\n \tThus the device can play multiple roles in everyday life. The project work can be made on full scale as well as scale down version, but in both cases the project is fully functional or working in nature.\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\n\r\n\r\n\r\nAutomobile Engineering Projects List - Abstract , Report\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )\r\n\r\n\r\n\r\n&nbsp;","headline":"Flywheel Based Battery Charger Mechanical Project","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2016-04-09","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2016\/04\/FlywheelBasedBatteryCharger-300x164.jpg","height":164,"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/electromagnetic-shearing-machine-mechanical-project/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2016/04/Manual_Electromagnetic_Shearing_Machine-2-249x300.jpg')"></div><span class="sr-only">link to ELECTROMAGNETIC SHEARING MACHINE MECHANICAL PROJECT</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/electromagnetic-shearing-machine-mechanical-project/">ELECTROMAGNETIC SHEARING MACHINE MECHANICAL PROJECT</a></p></header><div class="excerpt"><p>Project On Electromagnetic Shearing Machine - Mechanical Engineering

One such thing is industrial automation unit. In this automation units various machines those can be adopted easily are also getting \u00a0developed. Considering the example of piping industry (manufacture of small pipes) where plastic are PVc pipes are needed to be cut, shearing machines are used. There can be various types of shearing machines depending on parts to be cut process of cutting, \u00a0requirement of cutting length, etc. now a days hydraulic shearing machine, pneumatic shearing machine and mechanical type shearing machine are popular type of shearing machines used in above industries. These machines are certainly good at work but as with almost all types of machines there are certainly pros and cones association with them to for the purpose various work is being carried out to solve the dilema. In this project shearing m\/c of a new type i.e. electromagnetic shearing m\/c is decided to be fabricated. Along with it has also been decided to develop automation unit for the same so that m\/c can easily be adopted in todays automated plants.\r\n\r\n\r\n\r\nManual_Electromagnetic_Shearing_Machine-2\r\n\r\n\r\nINTRODUCTION\r\nThe project work assigned here with us is of building a shearing m\/c that is capable of shearing PVC \/ plastic \/ rubber pipes upto 6 mm in dia. Also it is pre-assigned work to furnish the same m\/c alongwith an automation unit as previously mentioned. As simple layout and tricky operational enables this type of m\/c to work practically at low cost, low maintenance, low capital investment in less space. It may be forecasted that in future this m\/c may have its unparallel place in the industry mentioned previously. The work is carried out using MDF (Medium Density Fiber) core hardwood plywood. Also some connecting components like studs are used the plunger is made up of high density polymer pipe and the core of electromagnetic is made up of again high density polymer pipe. Rest of the construction is made in MDF sheet cut to requirement. It can be noticed that in the fabrication of the project many parts are manufactured other than ferrous material. It is done so because ferrous is conductor of magnetism and controller be magnetised very easily for avoiding the flux generated for getting disturb with surrounding material.\r\n\r\nThe mat in surrounding is used the non ferrous. The only major component is the iron core which is needed to be made up of ferrous to get attracted to electromagnet when live next part that is fabrication out of ferrous is stud nut bolt. It is very necessary that for structural support that this part should be made in strength and support for solving the problem. It has been allowed to use ferrous material for the same. Also care have been taken to keep this ferrous material part away from electromagnet as for as possible.\r\n\r\nWhenever electromagnet is made live it sucks the iron core in between the cavity of the Electromagnetic because of high flux generated. This iron core there by pushes the plunger in the same direction which activates the cutter blade subassembly forcing the same in the blade subassembly forcing the same in the direction of material to be cut. This is simple procedure of cutting by this type of m\/c.\r\n\r\n\r\nAnother part of the project includes development of automation unit for running this m\/c on automation mode for cutting the mat as per required. This part include a Microcontroller a motor drives a relay driver etc\r\n\r\n&nbsp;\r\n\r\n\r\n\r\nMore Resources \/articles\r\nSheet Metal Fabrication Projects\r\nCutting , Hacksaw Machine Projects\r\nMachine Tool , Manufacturing Projects List - Abstract , Report\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )","headline":"ELECTROMAGNETIC SHEARING MACHINE MECHANICAL PROJECT","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2016-04-07","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2016\/04\/Manual_Electromagnetic_Shearing_Machine-2-249x300.jpg","height":300,"width":249},"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/how-to-calculate-heat-balance-shee/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2016/04/howtocalculateheatbalacesheetforicengine-300x121.jpg')"></div><span class="sr-only">link to How To Calculate Heat Balance Sheet For IC Engine</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/how-to-calculate-heat-balance-shee/">How To Calculate Heat Balance Sheet For IC Engine</a></p></header><div class="excerpt"><p>How To Calculate Heat Balance Sheet For IC Engine

Necessary information concerning the performance of the engine is obtained from the heat balance.\r\n\r\nThe performance of an engine is generally given by a heat balance sheet. To draw a heat balance sheet for the I.C. engine, it is run at constant load and constant speed. The Indicator diagram is drawn with the help of an indicator. The quantity of fuel used in a given time and its calorific value, the amount, inlet, and outlet temperature of cooling water and the mass of exhaust gases are recorded.\r\n\r\nThe heat balance sheet is generally done on a second basis or a minute basis or an hourly basis.\r\n\r\nThe engine should be equipped with a suitable loading arrangement to measure the brake power of the engine. Provisions are also made to measure the amount of air intake. amount of fuel consumed, the temperature of cooling water at inlet and outlet of the engine amount of cooling water circulated and temperature of exhaust gases.\r\n\r\n\r\nUse Of Heat Balance sheet :\u00a0\r\n1. To know an account of heat supplied and heat distributed in various ways in the system.\r\n2. To analyses the performance of the engine.\r\n\r\nHeat Balance Sheet Calculation :\u00a0\r\n\r\n\r\n\r\nThe heat balance is generally done on a second basis or a minute basis or an hourly basis.\r\n\r\nThe heat supplied to the engine is only in the form of fuel-heat and that is given by\r\n\r\nQs = mf X CV\r\n\r\nWhere mf is the mass of fuel supplied per minute or per sec. and CV is the lower calorific value of the fuel.\r\n\r\n\r\n\r\nThe various ways in which heat is used up in the system is given by\r\n\r\n(a) Heat equivalent of BP = kW = kJ\/sec. = kJ\/min.\r\n\r\n(b) Heat carried away by cooling water\r\n= Cpw X mw (Two \u2013 Twi) kJ\/min.\r\nWhere,\r\n\r\n \tmw is the mass of cooling water in kg\/min or kg\/sec circulated through the cooling jacket\u00a0\r\n \t(Two \u2013 Twi) is the rise in temperature of the water passing through the cooling jacket of the engine\u00a0\r\n \tCpw is the specific heat of water in kJ\/kg-K.\r\n\r\n(c) Heat carried away by exhaust gases\r\n= mg Cpg (Tge \u2013 Ta) (kJ\/min.) or (kJ\/sec)\r\n\r\nWhere,\r\n\r\n \tmg is the mass of exhaust gases in kg\/min. or kg\/sec and it is calculated by using one of the methods already explained.\r\n \tTg= Temperature of burnt gases coming out of the engine.\r\n \tTa = Ambient Temperature.\r\n \tCpg = Sp. The heat of exhaust gases in (kJ\/kg-K)\r\n\r\n(d) A part of the heat is lost by convection and radiation as well as due to the leakage of gases. Part of the power developed inside the engine is also used to run the accessories as a lubricating pump, camshaft and water circulating pump. These cannot be measured precisely and so this is known as unaccounted \u2018losses\u2019.\r\n\r\n\r\n\r\nHow to calculate heat Balance Sheet For IC Engine\r\n\r\n\r\nThe results of the above calculations are tabulated in a table and this table is known as \u201cHeat Balance Sheet\u201d. It is generally practice to represent the heat distribution as percentage of heat supplied. This is also tabulated in the same heat balance sheet.This unaccounted heat energy is calculated by the different between heat supplied Qs and the sum of (a) + (b) (c).\u00a0\r\n\r\n\r\n\r\n\r\n\r\nHeat Balance sheet Example :\u00a0\r\nProblem : An I.C. engine uses 6 kg fuel having calorific value 44000 kJ\/kg. in one hour. The brake power developed is 18kW. The temperature of 11.5 kg of cooling water found to rise through 25 0C per minute. The temperature of 4.2 kg of exhaust gas with specific heat 1 kJ\/kg K was found to rise though 220 0C. Draw heat balance sheet for the engine.\r\n\r\nAnswers :\u00a0\r\n\r\nSolution:\r\n\r\nGiven data :\r\nMass of Fuel = 6 Kg\/hr = 6\/60 = 0.1 Kg\/min.
