This lively and practical book looks at the enormous variety of machines and how they work. Fascinating and easy-to-do projects, such as making your own gears and belt drives, constructing a water-wheel and an Archimedean screw, or making your very own vacuum cleaner, will help you to understand the principles that are used to make machines work.
