WebWe would like to show you a description here but the site won’t allow us. 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… WebWhen expressed as a percentage, the thermal efficiency must be between 0% and 100%.
