This book arms engineers with the tools to apply key physics concepts in the field. A number of the key figures in the new edition are revised to provide a more inviting and informative treatment. The figures are broken into component parts with supporting commentary so that they can more readily see the key ideas. Material from "The Flying Circus" is incorporated into the chapter opener puzzlers, sample problems, examples and end-of-chapter problems to make the subject more engaging. "Checkpoints" enable them to check their understanding of a question with some reasoning based on the narrative or sample problem they just read. "Sample Problems" also demonstrate how engineers can solve problems with reasoned solutions.
