Description:

Pulley is a simple mechanical device used to lift heavy objects and save effort. Pulleys are divided into fixed pulley and moving pulley. The central shaft of the fixed pulley is fixed, and the central shaft of the moving pulley can be moved. Using fixed pulley does not save effort or distance, but it can change the direction of applying force. Using a movable pulley can save half the force, but it costs half the distance and cannot change the direction of applying the force. The fixed pulley and the movable pulley are combined to form pulley set, which not only saves effort but also changes the direction of applying force.
