What is the power?

What other familiar example have we of this kind of lever?
The fishing-rod is an example of this kind. One hand is the fulcrum, the other hand is the power, and the line, with the fish, is the weight. This is made plain by [Fig. 49], representing a lad just drawing a fish out of the water.
