What is an example of a third class lever as used in sports?

A baseball bat is an example of a third class lever because it operates on the principle where the effort is applied between the fulcrum and the load. In this case, the fulcrum is at one end of the bat (where the handle meets the barrel), the load is the ball at the opposite end when struck, and the effort is applied through the player’s hands as they swing the bat.

In a third class lever, the effort must be greater than the load to move it, which is typically seen in sports equipment designed for maximum range and speed, like a baseball bat. The setup allows players to generate higher speeds and greater distance when hitting the ball.

Other options, while related to mechanics, do not fit the specific definition of a third class lever as clearly as a baseball bat does. For instance, a pulley system is a type of simple machine that typically involves multiple ropes and does not conform to the standard lever classification. A see-saw represents a first class lever where the fulcrum is in the middle, and a door handle doesn't align with the effort, load, and fulcrum placement of a third class lever setup.
