Levers, like gears, pulleys, block and tackle, allows you to trade a long and weak movement for a shorter and stronger movement.

This is helpful when you want to move heavy objects.

A basic example is a pair of pliers. The handles will move a lot longer than the jaws, but the jaws will pinch a lot harder than you'd be able to do with your hands. That's the levers, or the leverage, allowing you to trade a long and weak movement for a short and strong movement.

Why do you have pulleys on the wells?

Pulleys exist on wells to make it easier to remove the bucket. Once the bucket has gone down to the water, it is heavy and hard to lift straight up.
