Although, mechanical advantage is less than 1 for class-three levers, we still use them. Give reason.

Text Solution

Verified by Experts

Although, mechanical advantage is less than 1 for calss-three levers, we still use them because the distance moved by the effort. For example, when a ball is hit with a bat, the ball ends up going faster than the speed with which the bat was swung. Therefore, class-three levers are called speed multipliers.
