The main objective of a basic mechanics course should be to develop in the engineering student the ability to analyze a given problem in a simple and logical manner and to apply to its solution a few fundamental and well-understood principles. This text is designed for a course that combines statics and mechanics of materialsor strength of materialsoffered to engineering students in the sophomore year.

In this text, the study of statics and mechanics of materials is based on the understanding of a few basic concepts and on the use of simplified models. This approach makes it possible to develop all the necessary formulas in a rational and logical manner, and to clearly indicate the conditions under which they can be safely applied to the analysis and design of actual engineering structures and machine components.

Practical Applications Are Introduced Early. One of the characteristics of the approach used in this text is that mechanics of particles is clearly separated from the mechanics of rigid bodies. This approach makes it possible to consider simple, practical applications at an early stage and to postpone the introduction of the more difficult concepts. As an example, statics of particles is treated first (Chap. 2); after the rules of addition and subtraction of vectors are introduced, the principle of equilibrium of a particle is immediately applied to practical situations involving only concurrent forces. The statics of rigid bodies is considered in Chaps. 3 and 4. In Chap. 3, the vector and scalar products of two vectors are introduced and used to define the moment of a force about a point and about an axis. The presentation of these new concepts is followed by a thorough and rigorous discussion of equivalent systems of forces, leading, in Chap. 4, to many practical applications involving the equilibrium of rigid bodies under general force systems.

New Concepts Are Introduced in Simple Terms. Because this text is designed for the first course in mechanics, new concepts are presented in simple terms and every step is explained in detail. On the other hand, by discussing the broader aspects of the problems considered and by stressing methods of general applicability, a definite maturity of approach is achieved. For example, the concepts of partial constraints and statical indeterminacy are introduced early and are used throughout.

Fundamental Principles Are Placed in the Context of Simple Applications. The fact that mechanics is essentially a deductive science based on a few fundamental principles is stressed. Derivations have been presented in their logical sequence and with all the rigor warranted at this level. However, the learning process being largely inductive, simple applications are considered first.

As an example, the statics of particles precedes the statics of rigid bodies, and problems involving internal forces are postponed until Chap. 6. In Chap. 4, equilibrium problems involving only coplanar forces are considered first and solved by ordinary algebra, while problems involving three-dimensional forces and requiring the full use of vector algebra are discussed in the second part of the chapter.

The first four chapters treating mechanics of materials (Chaps. 8, 9, 10, and 11) are devoted to the analysis of the stresses and of the corresponding deformations in various structural members, considering successively axial loading, torsion, and pure bending. The remaining five chapters (12 through 16) expand on what is learned in Chaps. 8 through 11. Chapter 12 begins with a discussion of the shear and bending-moment diagrams and then addresses the design of beams based on the allowable normal stress in the material used. The determination of the shearing stress in beams and thin-walled members under transverse loadings is covered in Chap. 13. Chapter 14 is devoted to the transformation of stresses and design of thin-walled pressure vessels. The determination of deflections in beams is presented in Chap. 15. Chapter 16, which treats columns, contains material on the design of steel, aluminum, and wood columns.
