PULLEY







         A pulley is made up of a grooved wheel


             and a rope around it.



         One side of the rope is connected to an

             object that can carry load and we lift the


             object by pulling on the other side of the


             rope using our own strength or a machine.

             The wheel moves and the load also


             moves.



         Pulley helps to lift loads.
