In this paper, the mechanical efficiency of mechanical systems is discussed. The influence of the arrangement of the different components of the mechanism and the power distribution over the different modules on the efficiency is investigated. Revolute, slider and contoured joints are studied. Sliding and rolling frictions are taken into account in order to determine their mechanical efficiency. Two numerical examples of a crank-connecting rod mechanism and a cam follower system are presented and the evolution of their mechanical efficiencies over a cycle are computed.
