This helpful volume explains what levers are and how to use them. Readers will learn to identify the different parts of a lever-fulcrum, load and effort. The book also explains the differences between first-, second- and third-class levers and explains why a seesaw is a first-class lever, but a fishing rod is a third-class lever.
