Answer 2

Pulley is used to change the direction of force or more specifically, tension in a rope without causing any change in magnitude.

For eg: Rope and pulley in wells. We give the force downwards. But pulley changes it's direction to up. Hence, the other end with water carrying bucket moves upwards.
