Question

4

A gym teacher is applying the principle of leverage in class. How is this MOST efficiently being demonstrated?

Answer 1

The gym teacher is demonstrating the principle of leverage by applying the force at the same point of the lever arm along the length of the lever or by maintaining the same angle between the lever arm and the applied force. A lever works by exerting a smaller force over a larger distance to lift a load with a larger force over a smaller distance.

Step-by-step explanation:

The gym teacher is demonstrating the principle of leverage by applying the force at the same point of the lever arm along the length of the lever or by maintaining the same angle between the lever arm and the applied force.

In practice, a lever works by exerting a smaller force over a larger distance to lift a load with a larger force over a smaller distance. The mechanical advantage of a lever is the ratio of the forces exiting and entering the machine.
