A wheel and axle is a disk and cylinder joined together. These two objects are only a simple machine when used in tandem. A wheel and axle is a modified first-class lever. When force is applied to the axle, the force is multiplied and transferred to the wheel. This causes the wheel to cover more area. Readers will learn about the invention of the wheel and axle, where wheels and axles can be found, and how they make difficult jobs easier.

Every time you turn on a faucet, ride a bike, or open a door, you're using a simple machine called a wheel and axle. This book uses clear text and practical, every-day examples to explain the physics behind the wheel and axle. Easy-to-read diagrams and large, vivid photographs aid understanding, and experiments encourage students to learn first-hand how this helpful simple machine works.

A hands-on approach introduces young scientists to wheels and axles. Science theory and practical, fun projects teach the physics and the technology behind this simple machine. Important science curriculum is explained through historical and contemporary examples of wheels and axles. Step-by-step projects range from the simple to the more challenging.

Readers likely use the wheel and axle machine every day in the form of doorknobs and faucet handles, but this fascinating invention is often overlooked. This book helps readers understand how the wheel and axle simple machine is all around them and helps build compound machines. Approachable text provides lasting knowledge about the forces that make these devices work. Bright full-color photographs including a picture gallery showing familiar objects using this simple machine aid readers in comprehending just how these mechanisms make tasks easier. The concepts in this book enhance a variety of elementary STEM curricula.
