This Second Edition of the highly successful textbook on mechanics has been updated and revised to include new and more practical material. The chapters on kinematics and mechanical oscillations have been rewritten and there is a new chapter on nonlinear behavior of some simple dynamical systems. Features more worked examples and exercises, improved diagrams and updated notation. In addition, sections describing numerical methods are now out of date and have been replaced by a modern computer-based approach. Problems to be solved on a microcomputer are now included.
