1. MECHANICAL TRANSMISSIONS Mechanical transmissions are devices suitably designed to transmit motion, as well as torques and forces, from a mechanical component to another component, modifying kinematic and dynamic input parameters – like angular velocit y, angular acceleration and torque (or force) – into output parameters having a different magnitude (e.g higher or lower angular speed, higher or lower torque magnitude, etc.) . The configurations and morphologies of mechanical transmissions are various. Ho wever, in most cases, a transmission has an input and an output shaft. Sometimes the angular velocity of the output shaft is equal, in magnitude and versus, to that of the input shaft. However, in general, the transmission transforms the input angular velo city, ωi, into a different output angular velocity, ωo, with ioω≥ω or ioω
