The heat capacity of material is the amount of heat transformed to raise unit mass of a material 1° in temperature. Thus Poisson’s ratio is higher in RUBBER.ġ2) What is the difference between heat capacity and specific heat of the material? Poisson’s ratio is a measure of the Poisson effect. This phenomenon is called thePoisson effect. When a material is compressed in one direction, it usuallytends to expand in the other two directions perpendicular tothe direction of compression. Thus on such high compression, gasoline gets highly compressed & it may blast.ġ1) Poissons Ratio is Higher in, Rubber/Steel/Wood? No, It will not work, as the Compression ratio of Petrol engine is 6 to 10 & that of Diesel engine is 15 to 22. Improving the surface finish by Polishing & providing residual stress by Shot peening.ġ0) What happens if gasoline is used in a Diesel Engine, Siesel Engine will work? and according to type of load we have to choose the type of bearing and that will give prior number of the bearing.ĩ) The Fatigue life of a part can be improved by? It is the measure of rating of CI engine.Ħ) Which Mechanism is used in Automobile gearing System?ħ) When Crude Oil is Heated, Which Hydro Carbon comes first?Ĩ) How to calculate Bearing number ti Diameter of the inner and outer?ĭivide the shaft diameter size by 5, it will give last two digit of the bearing no. It is the measure of rating of SI engine.Ĭetane No.- Cetane number is defined as the percentage, by volume, of n-cetane in the mixture of n-cetane and alpha methyl naphthalene. Octane No.- Octane number is defined as the percentage, by volume, of iso octane in the mixture of iso octane and h-heptane. Rear wheel sprocket works under the principle of ratchet and pawl.ĥ) Definition of Octane Number and Cetane Number? Also the exhaust passage takes more responsible for sound.Ĥ) Explain Bicycle Rear Wheel Sprocket working? Increases, entropy decreases.Ģ) Why different types of sound are produced in different bikes, though they run on SI Engines?Įngine specifications are different in different manufactures like as Bore Diameter (CC), Ignition timing.
1) Why Entropy decreases with increase in temperature?ĭs=dQ/T Entropy is inversely proportional to the temperature so, as temp.
