What materials make up the pulley system?

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.
