These in-depth books break down the mechanics of everyday engineering feats, from skyscrapers and airplanes to toilets. While engineering enthusiasts may find them fascinating, their primary use will be for research and classroom projects. Each section explains key engineering principles, providing readers with essential terminology, facts, and a clear understanding of how these structures and machines function. The text is dense, with most pages packed with information. Color photos serve to clarify concepts rather than to impress visually. The books include thought-provoking questions, facts, and primary source materials to support further study. A glossary, an index, and online resources for further reading round out each volume. VERDICT A solid addition to collections in need of engineering research materials.
