Note 2 — A TREATISE
Charles Caldwell translation
That form of lever, where the weight to be raised or the resistance to be overcome, is at one end, the force at the other, and the fulcrum or prop between them. This form is well represented by the handle of a pump, where the piston is the weight or resistance, the hand of the drawer of water the force, and the iron pin, on which the handle works, the fulcrum or prop.
