Third-class levers

In third-class levers, a small movement produces a large movement at the edge of the lever. The force moves between the fulcrum and the load.

Third-class levers do not make lifting a load easier. Instead, they produce large movements with small amounts of force. 

The arm is an example of a third-class lever. The small movements of the muscles make the arm move for longer distances.

Third class levers are useful for throwing things.

A fishing rod is an example of a third-class lever. The fulcrum is located in the fisher's belt, the left hand produces the force, and the load is provided by a large fish. 

A floorball stick is also an example of a third-class lever. The force is located at the centre of the level, whereas the fulcrum is found at its upper end. A small movement makes the ball travel with great force and speed.
