What is pulley and its uses?
A pulley is a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim. Pulleys are used singly or in combination to transmit energy and motion. One or more independently rotating pulleys can be used to gain mechanical advantage, especially for lifting weights.
How pulleys are used in everyday life?
Many types of exercise equipment use pulleys in order to function. Construction pulleys are used in order to lift and place heavy materials. Curtains at a theatre are moved using pulley systems that pull the curtains apart. Blinds on windows operate using a pulley system to move the blinds up and down.

What are the benefits of a pulley?
The main advantage in the use of pulleys is that the effort becomes less as compared to the normal lifting of the weights. In other words, it reduces the amount of actual force required to lift heavy objects. It also changes the direction of the force applied.
Do elevators have pulleys?
Pulleys with large metal cables are used in modern elevators. The cable is wrapped around a groove in the wheel and axle. An electric motor pulls the cable, lifting the car between floors. Several pulleys can be combined to reduce the necessary work to lift a load.
