How do rotary mechanisms work?

Rotary mechanisms convert linear motion into circular motion or vice versa, often using gears, levers, or cams. In these systems, a force applied in a straight line is transformed into rotational movement around a fixed axis. This is accomplished through components such as pulleys or gears that interlock and transmit motion. The efficiency and effectiveness of rotary mechanisms depend on the design and materials used, which can influence the speed, torque, and precision of the motion.
