From touch screens and security gates to bicycle gears and oboes, these books reveal how things work with the help of graphs, photographs and fun experiments. A scientific explanation with the help of annotated diagrams and illustrations is followed by examples of objects that make use of the mechanism. Try it! panels demonstrate how each mechanism works with the help of a simple exercise and D&T projects at the end of each book combine the mechanisms introduced throughout.
