Once the stones are cut, it is Harry's job to lift them onto a cart to be taken to the building site. These are massive stones and he will have difficulty lifting them.
What tools does Harry have available?
There are large timbers and rocks lying around the construction site. These are perfect parts for a lever!
We need this lever to increase our lifting force, therefore we will push one end of the lever under the resistance (Our stone), the fulcrum between the ends, and we will apply a downward force at the other end.
(It is usually easier for us to apply a downward force than it is to apply a lifting force.)
