Machines make work easier—helping break things apart, lift heavy objects, and change the power and direction of force applied to them. Simple Machines outlines different types of simple machines—wedges, wheels, levers, pulleys, and more—and gives common examples of how we use them every day. Clear, simple language is used to introduce important mechanical vocabulary, and easy-to-understand examples illustrate how we use machines to solve all kinds of problems.
