use large forces. Pulleys are as well assembled as part of belt and chain drives to be able to transmit power from one rotating shaft to another.
The pulley, a straightforward machine, really helps to perform work by changing the direction of forces and making easier the moving of large objects. … With this sort of pulley – known as a set pulley – pulling down on a rope makes an object surge off the ground. Additionally, there are movable pulleys and pulley systems.
