A text for an introductory mechanics course in undergraduate engineering programs, for students with background in algebra, geometry, trigonometry, calculus, and vector algebra. Chapters on general principles, concurrent force systems, statics of particles, internal forces, friction, and virtual work emphasize engineering and mathematical methods of analysis, and feature numerous color free-body diagrams, conceptual examples, worked problem examples, homework problems rated by difficulty, and computer problems. Includes an appendix on vector operations. Annotation copyright Book News, Inc. Portland, Or.
