    Part - 6 Most commonly asked Mechanical Interview Questions with answer

    Most commonly asked Mechanical Interview Questions  1.           Why Entropy decreases with increase in temperature? Ans.      ds=dQ/T Entropy is inversely proportional to the temperature so, as temp. Increases, entropy decreases. 2.            Why different types of sound are produced in different bikes, though they run on SI Engines? Ans.        Engine specifications are different in different manufactures like as Bore Diameter (CC), Ignition timing. Also the exhaust passage takes more responsible for sound. 3.            How much Watt means 1Hp? Ans.       746.2 Watt 4.            Explain Bicycle Rear Wheel Sprocket working? Ans.       Rear wheel sprocket works u...

    RADIOGRAPHY TEST

    RADIOGRAPHY TEST INTRODUCTION : Industrial radiography is a nondestructive test method that uses X-rays or Gamma rays to show the presence and certain characteristics of internal discontinuities in solid materials. The method is based on the ability of X-ray or Gamma-ray radiation to penetrate solids, to a degree that varies with such factors as wave length of the radiation, and type and thickness of the material part of the radiation penetrates the material and part is absorbed. The amount absorbed and the amount transmitted are a function of the thickness of the material. Where a void or discontinuity exists, there is essentially less material to absorb the radiation. This creates a different in absorption, a difference that registers on photographic emulsions. The result is a shadow picture called a radiography Radio-graphic Sources : The common gamma ray radio-graphic sources : Cobalt - 60 Cesium - 137 Iridium - 192 Thulium - 170 Gamma Ray Radiography : Gamma rays ar...

    Part -7 Most commonly asked Mechanical Interview Questions

    Most commonly asked Mechanical Interview Questions What are the different types of fits? Explain? On the basis of Indian standards fits can mainly be categorised into three groups: > Clearance Fit : These types of fits are characterised by the occurrence of a clearance between the two mating parts. The difference between the minimum size of the hole and the maximum size of the shaft is called the minimum clearance, the difference between the maximum size of the hole and the minimum size of the shaft is known as maximum clearance. > Interference Fit : In these types of fits the size of the mating parts are predefined so that interference between them always occurs. The tolerance zone of the hole is completely below the tolerance zone of the shaft. > Transition Fit : As the name suggests these type of fit has its mating parts sized limited to allow either clearance or interference. The tolerance zone of the hole and the shaft overlaps in case of such fits. For a shaf...
