เนื้อหาย่อ : Although essentially all engineering curricula require some course work in mechanics, the needs of the various engineering disciplines vary widely. This book is intended as a text for a first course in me- chanics for those students who require only a one- or two-semester course. It is the belief of the authors that the needs of these students can best be met by a broad, unified treatment of mechanics rather than an in-depth study of one or two specialized areas. The material contained in this book is an expanded version of Young's Introduc- tion to Applied Mechanics. Young's book was written primarily for nonengineering students, whereas the present text is designed primar- ily for engineering students. In the selection of specific subject matter, emphasis has been placed on topics which engineers with limited training in mechanics are most likely to find of value. Although the coverage is broad, an in-depth, rigorous treatment of the selected topics has been at- tempted and the material contained in the book is not intended as simply a "survey of mechanics." The text is organized into five major parts, each containing one or more chapters, as follows: Part I-Review Part II-Equilibrium Part III-Motion and Deformation Part IV-Rigid-Body Dynamics and Vibrations Part V-Engineering Materials and Applications Part I contains material normally found in calculus and physics courses which are presumed as prerequisites for a first course in me- chanics. However, it has been the authors' experience that ideas associated with forces and moments and topics such as elementary particle dynamics, centroids, moments of inertia, units, etc. need to be reviewed to reinforce the students' understanding of these elemen- tary but important facets of mechanics. Part II emphasizes the fundamental nature of equilibrium by con- sidering not only rigid bodies but equilibrium concepts applied to a continuum through the introduction of the concept of stress. Equi- librium of fluids is also treated in this section. Kinematics of particles, rigid bodies in plane motion, and de- formable bodies are included in Part III. The concept of strain is introduced, and the pertinent equations relating to strain transforma- tions and the measurement of strain are included. This section is followed in Part IV with a discussion of rigid body dynamics, with
