Mechanics of MaterialsThis text provides a clear, comprehensive presentation of both the theory and applications of mechanics of materials. The text examines the physical behaviour of materials under load, then proceeds to model this behaviour to development theory. The contents of each chapter are organized into welldefined units that allow instructors great flexibility in course emphasis. writing style, cohesive organization, and exercises, examples, and free body diagrams to help prepare tomorrow's engineers. The book contains over 1,700 homework problems depicting realistic situations students are likely to encounter as engineers. These illustrated problems are designed to stimulate student interest and enable them to reduce problems from a physical description to a model or symbolic representation to which the theoretical principles may be applied. The problems balance FPS and SI units and are arranged in an increasing order of difficulty so students can evaluate their understanding of the material.

Occasionally the design of a shaft depends on restricting the amount of rotation
or twist that may occur when the shaft is subjected to a torque. Furthermore,
being able to compute the angle of twist for a shaft is important when analyzing

I'm an engineering student currently using this book. It does a nice job of providing the relevent material on a subject in easy to understand rhetoric. It also is clear that the sequence of the material was done with thought.
