Answers are included. "First Class Lever" • A first-class lever is a lever in which the fulcrum is located between the input effort and the output load. • In operation, a force is applied (by pulling or pushing) to a section of the bar, which causes the lever to swing about the fulcrum, overcoming the resistance force on the opposite side. Levers make work much easier by using leverage, this multiplies the force. A lever is a bar that rests on a turning point (or pivot).
