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 materials—or strength of materials—offered 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. 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 diey can be safely applied to the analysis and design of actual engineering structures and machine components.
Free-body Diagrams Are Used Extensively. 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. A discussion of the application of the factor of safety to design can be found in Chap. Customary Units Is Consistently Maintained. Because it is essential that students be able to handle effectively both SI metric units and U. Since a large number of problems are available, instructors can assign problems using each system of units in whatever proportion they find most desirable for their class.
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. Thus, even when not covered in die course, diey are highly visible and can be easily referred to by the students if needed in a later course or in engineering practice. 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. 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 concept of stress at a point is introduced in Chap. 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 techniques—such as Mohr's circle—used 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 chapter ends with an optional section on nonprismatic beams Sec. Chapter 6 is devoted to the determination of shearing stresses in beams and thin-walled members under transverse loadings.
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. 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.
Thus, students are presented at an early stage with a method of solution that combines the analysis of deformations with the conventional analysis of forces used in statics. In this way. In addition, this approach helps the students realize that stresses themselves are statically indeterminate and can be computed only by considering the corresponding distribution of strains. The concept of plastic deformation is introduced in Chap.
Problems involving the plastic deformation of circular shafts and of prismatic beams are also considered in optional sections of Chaps. While some of this material can be omitted at the choice of the instructor, its inclusion in the body of the text will help students realize the limitations of the assumption of a linear stress-strain relation and serve to caution them against the inappropriate use of the elastic torsion and flexure formulas.
The determination of the deflection of beams is discussed in Chap. The first part of the chapter is devoted to the integration method and to the method of superposition, with an optional section Sec. This section should be used only if Sec. The second part of Chap. It presents the moment-area method in two lessons. Chapter 10 is devoted to columns and contains material on the design of steel, aluminum, and wood columns.
Chapter 11 covers energy methods, including Castigliano's theorem. The main objective of the study of the mechanics of materials is to provide the future engineer with the means of analyzing and designing various machines and load-bearing structures.
Both the analysis and the design of a given structure involve the determination of stresses and deformations. This first chapter is devoted to the concept of stress. Section 1. After a short discussion of engineering analysis and design , you will consider successively the normal stresses in a member under axial loading , the shearing stresses caused by the application of equal and opposite transverse forces , and the bearing stresses created by bolts and pins in the members they connect.
These various concepts will be applied in Sec. In Sec. In Chap. We also learned to design simple members and connections so that they would not fail under specified loading conditions. Another important aspect of the analysis and design of structures relates to the deformations caused by the loads applied to a structure. Clearly, it is important to avoid deformations so large that they may prevent the structure from fulfilling the purpose for which it was intended.
But the analysis ol deformations may also help us in the determination of stresses. Indeed, it is not always. This is because statics is based on the assumption of undeformable, rigid structures. By considering engineering structures as deformable and analyzing the deformations in their various members, ii will be possible for us to compute forces thai are statically indeterminate, i. Also, as we indicated in Sec. To determine die actual distribution of stresses within.
In this chapter, you will consider the deformations of a structural member such as a rod, bar, or plate under axial loading. In the two preceding chapters you studied how to calculate the stresses and strains in structural members subjected to axial loads, that is, to forces directed along the axis of the member.
In this chapter structural members and machine parts that are in torsion will be considered. More specifically, you will analyze the stresses and strains in members of circular cross section subjected to twisting couples, or torques, T and T'. These couples have a common magnitude 7, and opposite senses.
They are vector quantities and can be represented either by curved arrows. In the preceding chapters you studied how to determine the stresses in prismatic members subjected to axial loads or to twisting couples.
In this chapter and in the following two you will analyze the stresses and strains in prismatic members subjected to bending. Bending is a major concept used in the design of many machine and structural components, such as beams and girders.
This chapter will be devoted to the analysis of prismatic members subjected to equal and opposite couples M and M' acting in the same longitudinal plane. Such members are said to be in pure bending. In most of the chapter, the members will be assumed to possess a plane of symmetry. In the preceding chapter we learned to design beams lor strength. In this chapter we will be concerned with another aspect in the design of beams, namely, the determination of the deflection.
Of particular interest is the determination of the maximum deflection of a beam under a given loading, since the design specifications of a beam will generally include a maximum allowable value for its deflection. Also of interest is that a knowledge of the deflections is required to analyze indeterminate beams. These are beams in which the number of reactions at the supports exceeds the number of equilibrium equations available to determine these unknowns.
In the preceding chapters, we had two primary concerns: I the strength of the structure, i. In this chapter, our concern will be with Ihe stability of the structure, i. Our discussion will relate chiefly to columns, i. M echanics of Materials by R. Hibb eler. Dynamic Fracture Mechanics by Arun Shukla.

- Плеснуть чуточку водки. - No, gracias. - Gratis? - по-прежнему увещевал бармен. - За счет заведения. Превозмогая шум в голове, Беккер представил себе грязные улицы Трианы, удушающую жару, безнадежные поиски в долгой нескончаемой ночи. Какого черта.
В чем же тогда проблема. В отчет вкралась какая-то ошибка? - Мидж промолчала. Джабба почувствовал, что она медлит с ответом, и снова нахмурился. - Ты так не считаешь.
Аккуратно, предмет за предметом, перетряхнул одежду. Затем взял ботинки и постучал каблуками по столу, точно вытряхивая камешек. Просмотрев все еще раз, он отступил на шаг и нахмурился. - Какие-то проблемы? - спросил лейтенант. - Да, - сказал Беккер.
В Третий узел заглянул Стратмор. - Какие-нибудь новости, Сьюзан? - спросил Стратмор и тут же замолчал, увидав Грега Хейла. - Добрый вечер, мистер Хейл.
Панк пристально смотрел на. - Вы похожи на полицейского. - Слушай, парень, я американец из Мериленда. Если я и полицейский, то уж точно не здешний, как ты думаешь. Эти слова, похоже, озадачили панка.
Это имя так просто превращается в Танкадо. И лучшие в мире специалисты-криптографы этого не поняли, прошли мимо, на что он и рассчитывал. - Танкадо посмеялся над нами, - сказал Стратмор. - Вы должны отключить ТРАНСТЕКСТ, - напомнила Сьюзан.
Он зря мне доверился. Ключ стоит в сотни раз больше того, что он платит мне за его хранение. - Извините, но ваш ключ сам по себе ничего не стоит. Как только Танкадо узнает о том, что вы сделали, он опубликует свою копию, и рынок рухнет.
Конечно. Он работает уже шестнадцать часов, если не ошибаюсь. Чатрукьян не знал, что сказать.
Это приказ. Чатрукьян пнул ногой урну и выругался вслух - благо лаборатория была пуста: - Диагностика, черт ее дери. С каких это пор заместитель директора начал действовать в обход фильтров. Сотрудникам лаборатории платили хорошие деньги, чтобы они охраняли компьютерные системы АНБ, и Чатрукьян давно понял, что от него требуются две вещи: высочайший профессионализм и подозрительность, граничащая с паранойей. Черт возьми! - снова мысленно выругался .
Какая разница? - огрызнулся светловолосый. - Позвольте вам сразу кое-что объяснить, - сказал директор. Секунду спустя оба, залившись краской, делали доклад директору Агентства национальной безопасности.
