Athird class lever has a mechanical advantage of < 1. what is an example of a third class lever and why use it? a) pulley; changes direction b) baseball bat; increases velocity c) car jack; increases the weight it can lift d) wheel barrow; makes it easier to move a load

B.) Baseball bat; increases velocity

All third class levers have a mechanical advantage less than 1. Since the output end has a longer distance from the fulcrum than the input point, the output end moves at a greater velocity than the input point. Because of this, third class levers are commonly used when trying to hit an object with as much velocity as possible.
