This text offers a clear exposition of the dynamics of mechanical systems from an engineering perspective. Basic concepts are thoroughly covered, then applied in a systematic manner to solve problems that have recognizable applications to engineering practice.Theoretical discussions are illustrated by numerous examples, and each chapter offers a wealth of homework problems. In this new edition the author has revised sections to enhance understanding and added examples as well as homework problems. The new edition also contains a thorough development of computational methods for solving the differential equations of motion for constrained systems.
