Mechanical efficiency

In mechanical engineering, mechanical efficiency is a dimensionless number that measures the efficiency of a mechanism or machine in transforming the power input to the device to power output. A machine is a mechanical linkage in which force is applied at one point, and the force does work moving a load at another point. At any instant the power input to a machine is equal to the input force multiplied by the velocity of the input point, similarly the power output is equal to the force e… WebEfficiency of engine: These are the main efficiencies used to check engine performance. 1.
