How do pulleys work? - Explain that Stuff
WEBNov 17, 2023 · A pulley is simply a collection of one or more wheels over which you loop a rope (or chain) to make it easier to lift things. Here's an everyday example: Photo: A pulley mounted on a huge lifting frame to make it safer to use.
Pulley - Wikipedia
WEBA 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.

WEBA 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.
