Pulleys are also assembled as part of belt and chain drives in order to transmit power in one rotating shaft to some other.
The pulley, a straightforward machine, helps to perform work by changing the direction of forces and making easier the moving of huge objects. … With this sort of pulley – called a fixed pulley – pulling down on a rope makes an object climb off the ground. Additionally, there are movable pulleys and pulley systems.
