Pulleys are likewise assembled within belt and chain drives in order to transmit power in one rotating shaft to another.
The pulley, a simple machine, really helps to perform work by changing the route of forces and making easier the moving of huge objects. … With this type of pulley – known as a set pulley – pulling down on a rope makes an object go up off the ground. Additionally, there are movable pulleys and pulley systems.
