Mechanical Transmissions: Functions and Mechanisms

This lecture covers the fundamental concepts of mechanical transmissions, including motion transformation, speed variation, and force/torque transmission ratios. It explores mechanisms such as connecting rod-crank, rectilinear development, conical friction, and wheel and worm. The instructor explains the concept of irreversibility in systems and the energy losses in transmissions, emphasizing the importance of understanding the input-output relationship in mechanical devices.
