Pulleys are likewise assembled within 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 way of forces and producing easier the moving of significant objects. … With this kind of pulley – called a fixed pulley – pulling down on a rope makes an object climb off the ground.
