Review: 

The subtitle of the book is “Where Engineering and Mathematics meets”; indeed, one of the authors is an engineer and the other is a mathematician. The book illustrates how physical models can be created from mathematical ones. To be more precise, the book is devoted to various relations between geometry and mechanics. Various topics, presented in 13 chapters, include construction of linkages producing exact and approximate movements along straight lines and other curves, balancing bodies and dissecting and recomposing planar figures. The topics treated in the book are usually first briefly explained from the (correct) geometrical point of view and then applied to physical constructions. The book is very nicely printed and contains many nice figures and photographs of physical models, as well as an extensive bibliography. It can be recommended as a formal or recreational lecture both for mathematicians and engineers.
