Statically indeterminate problems are first discussed in Chap. 2 and considered throughout the text for the various loading conditions encountered. 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 the first course in mechanics of materialsor strength of materialsoffered to engineering students in the sophomore or junior year. The authors hope dial it will help instructors achieve this goal in that particular course in the same way that meir other texts may have helped them in statics and dynamics. In this text the study of the mechanics of materials is based on the understanding of a few basic concepts and on the use of simplified models. ![]() Throughout the text free-body diagrams are used to determine external or internal forces. The use of picture equations will also help the students understand (he superposition of loadings and the resulting stresses and deformations. Design Concepts Are Discussed Throughout the Text Whenever Appropriate. A discussion of the application of the factor of safety to design can be found in Chap. Topics such as residual stresses, torsion of noncircular and thin-walled members, bending of curved beams, shearing stresses in non-symmetrical. To preserve the integrity of the subject, these topics are presented in the proper sequence, wherever they logically belong. For convenience all optional sections have been indicated by asterisks. It is expected that students using this text will have completed a course in statics. However. Chap. 1 is designed to provide them with an opportunity to review the concepts learned in that course, while shear and bending-momenl diagrams are covered in detail in Sees. The properties of moments and centroids of areas are described in Appendix A; this material can be used to reinforce the discussion of the determination of normal and shearing stresses in beams (Chaps. The first four chapters of the text 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. Each analysis is based on a few basic concepts, namely, the conditions of equilibrium of the forces exerted on the member, the relations existing between stress and strain in the material. The study of each type of loading is complemented by a large number of examples, sample problems, and problems to be assigned, all designed to strengthen the students understanding of. ![]() The fact that stresses depend upon the orientation of the surface on which they are computed is emphasized again in Chaps. However, the discussion of computational techniquessuch as Mohrs circleused for the transformation of stress at a point is delayed until Chap. The discussion in Chap. Also, the study of beams under transverse loads is covered in two separate chapters. Chapter 5 is devoted to the determination of the normal stresses in a beam and to the design of beams based on the allowable normal stress in the material used (Sec. The chapter begins with a discussion of the shear and bending-moment diagrams. The formula for the shear How, q VQI, is derived in the traditional way. More advanced aspects of the design of beams, such as the determination of the principal stresses at the junction of the flange and web of a W-heam, are in Chap. Chap. 7. The design of transmission shafts is in that chapter for the same reason, as well as the determination of stresses under combined loadings that can now include the determination of the principal stresses, principal planes, and maximum shearing stress at a given point. Statically indeterminate problems are first discussed in Chap.
