    Sure. Dogs, horses, people, or elephants, etc. walking on a treadmill or turning a windlass. Waterwheels. The possibilities are quite numerous.

    Welcome to the PF.

    As you say, it is your schoolwork project. So you must show some effort on your part before we can be of tutorial help. What are your thoughts? What is the exact statement of the project?

    The original lifts in the Eiffel Tower were operated by a multiple pulley system. The counter balance weights were solid blocks of concrete in chambers underground. When the chambers were filled with water the buoyancy resulted in a small movement of the concrete blocks and the lift moving a long way up the tower.
