Crank shaft is one of the vital components of the engine which is greatly stressed and subjected to bending and torsional loads. It works with fourlink mechanism converting reciprocal displacement of piston to rotatory motion. The design and operational efficiency of crankshaft determines the life span for an engine. Let us consider a single cylinder four stroke cycle engine which is an Internal Combustion Engine (IC Engine).

                     An IC engine works on slider-crank mechanism its constituents being a crank shaft, con ... Read more »
