How is Pulley different from wheel and axel

Answers

Answered by nishma86

Answer:

Pulley is used to change the direction of a rope or a chain. The actual rotation of the pulley wheel is a side effect. Wheel and axle are used to amplify rotational force. The force can be provided through a rope wrapped around the wheel, but the change of direction is a side effect.
