1. What are the main parts of a lever?

A catapult or pair of pliers

A solid board and a fulcrum or pivot point

A fulcrum, an applied force, and a load.

2. What determines the class of a lever?

Where the load and effort are with respect to the fulcrum

How much effort is required to lift the load

Whether the arms are long, medium or short in length

3. What is a common use for a lever?

To increase force, distance, and speed at the same time

To measure friction

To lift a heavy load

If you got all three correct, you are on your way to becoming a Champion in Understanding Machines. If you had problems, you had better look over the material again.
