If the pull on the bolt is 14000 kg, the diameter of the bolt should be 60 mm.\r\n10.\u00a0 In case knuckle joint the pin is most likely to fail in double shear.\r\n11.\u00a0 The key is cut is both shaft and hub is case of sunk key.\r\n12.\u00a0 Splines are used when axial relative motion between shaft and hub is necessary.\r\n13.\u00a0 Splined shafts are generally used in automobiles.\r\n14.\u00a0 Universal coupling\/Hook\u2019s joint is used for non-collinear shafts.\r\n\r\n&nbsp;\r\n\r\nmachine design basic gate\r\n\r\n15.\u00a0 In flange coupling the weakest element should be key.\r\n16.\u00a0 Turn buckle has left hand threads on one end and right hand threads on other end.\r\n17.\u00a0 Elastic nut is a locking device that has hard fiber or nylon cotter is recessed in the nut and becomes threaded as the nut is screwed on the bolt causing a tight grip.\r\n18.\u00a0 Treating the weld as a line, the moment of inertia about center of gravity of a circular weld of diameter d, would be \u03c0d3\/4.\r\n19.\u00a0 A single ply leather belt running at a belt velocity of 300 ft\/min is likely to transmit per inch of width 4.0 HP.\r\n20.\u00a0 For butt welding of two plates each of which is 25 mm thick, the best process would be electro slag welding.\r\n21.\u00a0 The compression members tend to buckle in the direction of least radius of

journal.\r\n28.\u00a0 If P = bearing pressure on projected bearing area, z = absolve viscosity of lubricant, and N = speed of journal, then the characteristic number is given by ZN\/p.\r\n29.\u00a0 The rated life of bearing changes inversely as cube of load.\r\n30.\u00a0 The oiliness bearing does not need external supply of lubricant.\u00a0 \r\n31.\u00a0 In cross or regular lay ropes direction of twist of in stands is opposite to the direction of twist of stands.\r\n32.\u00a0 Gears for wrist watches are generally manufactured by helix angle.\r\n33.\u00a0 The type of cam used for low and moderate speed engines is generally harmonic\r\n34.\u00a0 The form coefficient of a spring is capability to store energy.\r\n35.\u00a0 Coriolis component of acceleration is found in wit worth-quick return motion\r\n36.\u00a0 Cold working of material increase the fatigue strength.\r\n37.\u00a0 A Babbitt is antimony bearing lead or tin alloy\r\n38.\u00a0 Addendum of a cycloidal gear tooth is epicycloids\r\n39.\u00a0 Spiral gears are suitable for transmitting small powers\r\n40.\u00a0 As pump speed increases its NPSH (Net Positive Suction Head) requirement increases\r\n41.\u00a0 If pump NPSH requirements are not satisfied, it will be cavitated\r\n42.\u00a0 Bush roller chain is used in motor cycle.\r\n43.\u00a0 The working load for a chain for crane application is expressed in terms of diameter of link in cm and given by 500 multiplied by square of diameter.\r\n44.\u00a0 If a square key and shaft are to be of the same material and or of equal strength, the length of key would be 1.23d, d=diameter of shaft\r\n45.\u00a0 In a standard coarse thread bolt the stress concentration is maximum at root.\r\n46.\u00a0 Fatigue strength of a surface may be increased by polishing the surface\r\n47.\u00a0 The maximum deflection allowed in gantry girders is L\/1000\r\n48.\u00a0 The maximum size of the fillet weld that can be used at 3 mm\r\n49.\u00a0 The maximum size of fillet weld that can be made in single pass in 6 mm\r\n50.\u00a0 A rolled steel flat designated as 50 ISF 8 means the flat is 50 mm wide and 8 mm thick.\r\n51.\u00a0 The column splice is used for increasing length of column\r\n52.\u00a0 The minimum thickness steel member exposed to weather and accessible for painting is 10 mm\r\n53.\u00a0 For determination of allowable stress in axial compression, IS: 800-1962 has adopted secant formula\r\n54.\u00a0 For accurately, cut gears operating at velocities upto 20 m\/sec, the velocity factor v, is given by

The amount of pollution that all cars produce together can create big problems. The amount of pollution that all cars produce together can cause big problems. Government created laws that restrict the amount of pollution that cars produce to solve it. Auto makers have made many improvements to car engines and fuel systems to keep up with these laws. In 1975, an interesting device called catalytic converter was created. The device, converts harmful pollutants into less harmful emissions before they ever leave the car\u201fs exhaust system.\r\n\r\nThe exhaust from the combustion in a car engine is comprised of six main ingredients:\r\n1. Nitrogen gas, Carbon dioxide and water vapor are the three of the main emissions. These gases do not cause damage to the atmosphere.\r\n2. Carbon Monoxide, other hydrocarbons and Nitrogen Oxides result in a majority of the pollution caused by cars.\u00a0\r\n\r\n \tCarbon monoxide is a colorless and odorless gas that can kill you if too much is inhaled\r\n \tHydrocarbons are produced during incomplete combustion and these hydrocarbons can be broken down by the sun, creating ground level Ozone, also known as smog.\r\n \tNitrogen Oxides can cause acid rains.\r\n\r\nCatalytic convertors are designed to reduce these last three emissions.\r\nConstruction:\r\nThe core is often a ceramic\/stainless steel foil honeycomb.\r\n- Increases the amount of surface area\r\n- Support the catalyst. Also called \u201ccatalyst support\u201d.\r\n\r\n\r\n\r\nCatalytic converter for cars\r\n\r\n\r\n\r\nA wash coat is used to make converters more efficient because a mixture of silica and alumina will form a rough and irregular surface which leads to more surface area. Therefore, more places for active precious metal sites. The catalyst is added to the wash coat before applied to the core.\r\nPlatinum is the most active catalyst and is widely used. Other materials such as palladium and rhodium have also been used.\r\n\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nHeat Transfer Notes , Article , Interview Que. and Ans.\r\nManufacturing Technology Notes , Articles\r\nMechanical Subjectwise Basic Concept Notes ,Articles","headline":"Seminar and Project on Catalytic converter for cars","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/m.gunkrazy.com\/"},"datePublished":"2015-03-31","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/m.gunkrazy.com\/wp-content\/uploads\/2015\/03\/Catalyticconverterforcars-300x194.jpg","height":194,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/m.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="//m.gunkrazy.com/classification-or-types-of-automobiles/" rel="nofollow"><div class="image-container" style="background-image: url('//m.gunkrazy.com/wp-content/uploads/2015/03/classification2520of2520Automobiles-300x225.jpg')"></div><span class="sr-only">link to Classification Or Types of Automobiles with examples</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//m.gunkrazy.com/classification-or-types-of-automobiles/">Classification Or Types of Automobiles with examples</a></p></header><div class="excerpt"><p>Classification Or Types of Automobiles with examples

Arc welding and ox-acetylene welding are the two usual methods adopted. Molten or fused metal is deposited between the metal parts which are to be connected. The metal parts are also fused to a speci\ufb01ed depth. When the deposited fused metal is cooled, the metal parts get joined by new metal. The ends of metal parts to be connected and the tip of the weld rod are fused by arc which causes a high temperature of about 3300 degree Celsius.\u00a0 In the ox-acetylene method a jet of burning oxygen and acetylene is used as a source of heat. The weld rod has a coating which also melts during the welding process and forms a shield preventing combination of the heated metal with the freely available oxygen and nitrogen from the atmosphere.\r\n\r\n\r\n\r\nFig. Gas metal arc welding (MIG welding)\r\n\r\n\r\n\r\nADVANTAGES OF WELDED CONNECTIONS\u00a0\r\n(I)\u00a0 Since the process does not involve driving holes, the gross sectional area of the welding members is effective. In the case of riveted tension member deductions have to be made for the area lost due to punching holes.\r\n\r\n(ii) Welded structures are comparatively lighter than corresponding riveted structure.\u00a0\u00a0\r\n\r\n(iii) A welded joint has a great strength. Often a welded joint has the strength of the parent metal itself.\u00a0\r\n\r\n(iv) Repairs and further new connections can be done more easily than in riveting.\r\n\r\n(v) Welded joints provide rigidity. Hence welded members for the same loading, are n smaller bending moments than corresponding riveted members.\u00a0\u00a0\r\n\r\nvi) Often welded joints are economical to riveted joints. For a welded structure maintenance and painting costs are lesser than for the riveted structure.\r\n\r\n( Vii) Members of such shapes that afford dif\ufb01culty for riveting can be more easily welded.\r\n\r\n(viii) A welded structure has a better \ufb01nish and appearance than the corresponding riveted structure\r\n.\r\n(ix) Connecting angles, gusset, plates, splicing plates can be minimized and in many cases, can be avoided in welded structures.\r\n\r\n(x) Steel bars in reinforced concrete structures may be welded easily. Lapping of bars may be avoided if welding is resorted to.\u00a0\r\n\r\n(X!) It is possible to weld at any point at any part of a structure. But riveting will always require enough clearance.\u00a0\r\n\r\n(xii) The process of welding does not involve great noise compared to the noise produced in the riveting process.\r\n\r\nDISADVANTAGES OF WELDED CONNECTIONS\u00a0\r\n\r\n(1) Welding requires skilled labour and supervision.\u00a0\r\n\r\n(ii) Testing a welded joint is dif\ufb01cult. An X-ray examination alone can enable us to study the quality of the connection.\r\n\r\n(iii) Due to uneven heating and cooling, the welded members are likely to get warped at the welded surfaces.\r\n\r\n(iv) Internal stresses in the weldedzones are likely to be set up.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\u00a0\r\n\r\nMore Resources \/articles\r\nManufacturing Technology Notes , Articles\r\nCAD Software | CAD Tutorials\r\nThermal Engineering - Articles , Notes , Interview Q &amp; A\r\nMechanical Subjectwise Basic Concept Notes ,Articles","headline":"Welding process l Advantages and Disadvantages of welding Connections","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/m.gunkrazy.com\/"},"datePublished":"2015-03-30","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/m.gunkrazy.com\/wp-content\/uploads\/2015\/03\/welding2520process2520.jpg","height":248,"width":220},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/m.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="//m.gunkrazy.com/types-of-transmission-system/" rel="nofollow"><div class="image-container" style="background-image: url('//m.gunkrazy.com/wp-content/uploads/2015/03/semi2520automatic2520transmission-300x225.jpg')"></div><span class="sr-only">link to Types of Transmission system l Comparison between manual and automatic transmission</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//m.gunkrazy.com/types-of-transmission-system/">Types of Transmission system l Comparison between manual and automatic transmission</a></p></header><div class="excerpt"><p>Types of Automobile Transmission system:

Manual Transmission\r\n2. Automatic Transmission\r\n3. Semi-automatic Transmission :-\r\na) Dual-cutch Transmission\r\nb) Sequential Transmission\r\n4. Continuously Variable Transmission\r\n\r\n\r\nBefore this you should visit here to get detailed information about automatic transmission\r\nWhat is Automatic transmission - trends in automobile\r\n\r\n\r\nAutomatic transmission and a manual transmission accomplish exactly the same thing, but they do it in totally different way.\r\n\r\n\r\nsemi automatic transmission\r\n\r\n\r\nAdvantages of manual transmission over automatic transmission-\r\n\r\n\r\n1. It is easier to build a strong manual transmission than an automatic one. This is because a\u00a0manual system has one clutch to operate, whereas an automatic system has a number of clutch packs that function in harmony with each other.\r\n2. Manual transmissions normally do not require active cooling, because not much power is\u00a0dissipated as heat through the transmission.\r\n3. Manual gearshifts are more fuel efficient as compared to their automatic counterpart. Torque\u00a0convertor used to engage and disengage automatic gears may lose power and reduce acceleration as well as fuel economy.\r\n4. Manual transmissions generally require less maintenance than automatic transmissions. An automatic transmission is made up of several components and a breakdown of even a single\u00a0component can stall the car completely.\r\nAdvantages of automatic transmission over manual transmission-\r\n1. The manual transmission locks and unlocks different sets of gears to the output shaft to achieve the various gear ratios, while in an automatic transmission; the same set of gears produces all of the different gear ratios. The planetary gearset is the device that makes this possible in an automatic transmission.\r\n2. Automatic cars are easier to use, especially for the inexperienced car driver. Manual system requires better driving skills, whereas with an automatic, the clever system does it all on its own.\r\nThis holds a greater advantage for new and inexperienced drivers and also helps during congested traffic situations where it becomes difficult to change gears every second.\r\n3. Automatic transmission requires less attention and concentration from the driver because the automatic gears start functioning as soon as the system feels the need of a gear change. For car with manual gear shifts, the driver has to be more alert while driving and better coordinated.\r\n4. There is no clutch pedal and gear shift in an automatic transmission car. Once you put the transmission into drive, everything else is automatic.\r\n5. Automatic cars have better ability to control traction when approaching steep hills or engine braking during descents. Manual gears are difficult to operate on steep climbs.","headline":"Types of Transmission system l Comparison between manual and automatic transmission","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/m.gunkrazy.com\/"},"datePublished":"2015-03-28","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/m.gunkrazy.com\/wp-content\/uploads\/2015\/03\/semi2520automatic2520transmission-300x225.jpg","height":225,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/m.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=324">&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=323"><span class="screen-reader-text">Page </span>323</a> <a class="page-numbers" href="?page_num=324"><span class="screen-reader-text">Page </span>324</a> <span aria-current="page" class="page-numbers current"><span class="screen-reader-text">Page </span>325</span> <a class="page-numbers" href="?page_num=326"><span class="screen-reader-text">Page </span>326</a> <a class="page-numbers" href="?page_num=327"><span class="screen-reader-text">Page </span>327</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=326">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('//m.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.
