[0002] In mechanics, a typical pulley is a round wheel that can rotate around a central axis, and has a groove on the circumference of the round wheel. A rope is wound around the groove, and pulling either end of the rope will cause the round wheel to rotate around the central axis due to the friction between the rope and the round wheel. A pulley is actually a deformed, rotatable lever, and its main functions include pulling a load, changing the direction of force, transmitting power, etc. A mechanism composed of multiple pulleys is called a "pulley block" or "compound pulley". A pulley block can pull a heavy load due to its mechanical advantage. A pulley can also be used as a component of a chain drive or a belt drive to transmit power from one rotating shaft to another rotating shaft. According to whether the central axis of the pulley moves or not, the pulley can be divided into a "fixed pulley" and a "movable pulley". The central axis of the fixed pulley is fixed, while the central axis of the movable pulley can move. Each type of pulley has its own advantages and disadvantages. A pulley block can be formed by assembling a fixed pulley and a movable pulley together. A pulley block not only saves effort but also changes the direction of force.
