A pulley is a wheel on an axle or shaft enabling a taut cable or belt passing over the wheel to move and change direction, or transfer power between itself and a shaft. A sheave or pulley wheel is a pulley using an axle supported by a frame or shell ( block) to guide a cable or exert force.

This physics video tutorial provides a basic introduction into the pulley - a simple machine that offers a mechanical advantage by increasing the force needed to lift an object through the use of...
A pulley is a device that can increase the magnitude of an effort force . Without Pulley. With no pulley - the effort force is similar to the load - in opposite direction. S = F (1) where. S = effort force (N, lb) F = load (N, lb) Single Pulley. Fixed Pulley.
A pulley is a system of rope looped over one or more wheels to make it easier to lift heavy objects. Pulling the rope downward creates an upward force on the load. There are three basic systems of pulleys: A fixed pulley has a wheel that is secured in a single spot and changes the direction of the force needed to lift an object.
