This combination of efficiency and precision makes compound pulleys highly effective in various lifting applications.

To write a rule that relates the number of pulleys, input force, and output force, you can use the formula for mechanical advantage (MA) in a pulley system. The mechanical advantage is equal to the ratio of the output force (load) to the input force (effort): MA = Output Force / Input Force. In a pulley system, the mechanical advantage is also equal to the number of supporting ropes, which is determined by the number of pulleys used. Thus, you can express it as: Output Force = Input Force × Number of Pulleys.

A typical pulley system consists of several key materials: the pulley wheel, which is often made of metal or durable plastic for strength and smooth rotation; the rope or cable, typically made from synthetic fibers, steel wire, or natural materials like hemp; and the mounts or brackets, usually constructed from metal or reinforced plastic for stability. Additionally, bearings may be included to reduce friction and enhance the system's efficiency. Together, these components allow the pulley system to lift and move loads effectively.
