    Part -8 Most commonly asked Mechanical Interview Questions

    Most commonly asked Mechanical Interview Questions  ·          What happens if gasoline is used in a Diesel engine?Diesel engine will work ? No, It will not work,as the Compression ratio of Petrol engine is 6 to 10 & that of Diesel engine is 15 to 22 . Thus on such high compression, gasoline gets highly compressed & it may blast. ·          Which Mechanism is used in Automobile gearing system Differential mechanism ·           Why different types of sound are produced in different bikes though they say run on SI engine Engine specifications are different in different manufactures like as Bore Diameter(CC), Ignition timing.Also the exhaust passage take more responsible for sound. ·           Why entropy decreases with the increase in temperature? ds=dQ/T Entropy is inversely proportional to the temperatu...

    CHARPY V NOTCH IMPACT TEST

    CHARPY V NOTCH IMPACT TEST Object : To determine the amount of energy absorbed in fracturing a standardized test piece at a specified temperature. Method : A machined, notched specimen is broken by one blow from a pendulum. Because scatter occurs in the results, at least three specimens are used to assess the joint represented. Testing is carried out at a temperature specified in the appropriate application standard. Reporting Results: Location and orientation of the notch.  Testing temperature. Energy absorbed in joules.  Description of fracture appearance. Location of any defects. The Charpy impact test, measured in joules, is an assessment of TOUGHNESS. Transition temperature (curve) in steel.

    FILLET WELD FRACTURE TEST

    FILLET WELD FRACTURE TEST Object :  To break the joint through the weld to permit examination of the fracture surfaces for flaws and to check root penetration and fusion. Method: The specimen is cut to length and a saw cut, normally 2 mm deep, is made along the center of the weld face. The specimen is fractured by bending or hammer blows. Reporting Results: Thickness of parent material.  Throat thickness and leg length.  Location of fracture. Appearance of joint after fracture. Depth of penetration / lack of penetration or fusion.
