    MAGNETIC PARTICLE EXAMINATION (M.P.I.)

    MAGNETIC PARTICLE EXAMINATION (M.P.I.) INTRODUCTION This method is used for detecting cracks and other discontinuities open to surface or sub surface in ferromagnetic materials. Fine magnetic particles are applied to the surface of a part which has been suitably magnetized. The particles are attracted to regions of magnetic non-uniformity associated with defects and discontinuities, thus producing indication which are observed visually. PRINCIPLE When a piece of metal is placed in a magnetic field and the lines of magnetic flux get intersected by a discontinuity such as a crack or slag inclusion in a casting, magnetic poles are induced on either side of the discontinuity. The discontinuity causes an abrupt change in the path of magnetic flux flowing through the casting normal to the discontinuity, resulting a local flux leakage field and interfering with the magnetic lines of force. This local flux disturbance can be detected by its affect upon magnetic particles that collect o...

    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...
