Pulleys

Pulleys are simple machines consisting of a wheel with a grooved rim and a central hub, often used in conjunction with a belt or chain. They are integral components in various systems for the purpose of transmitting mechanical power or changing the direction of force. The basic design of a pulley involves a wheel mounted on an axle, and the groove on the rim provides a surface for a belt or rope to move along.
Pulleys come in various types, including fixed pulleys (stationary), movable pulleys (able to move along an axis), and compound pulleys (combinations of fixed and movable pulleys). The effectiveness of pulleys in mechanical systems makes them crucial components in industries ranging from manufacturing and transportation to construction and more.
