This capacity requires more than a mere knowledge of the physical and mathematical principles of mechanics; also required is the ability to visualize physical configurations in terms of real materials, actual constraints, and the practical limitations which govern the behavior of machines and structures.
One of the primary objectives in a mechanics course is to help the student develop this ability to visualize, which is so vital to problem formulation. Indeed, the construction of a meaningful mathematical model is often a more important experience than its solution. Maximum progress is made when the principles and their limitations are learned together within the context of engineering application. There is a frequent tendency in the presentation of mechanics to use problems mainly as a vehicle to illustrate theory rather than to develop theory for the purpose of solving problems.
When the first view is allowed to predominate, problems tend to become overly idealized and unrelated to engineering with the result that the exercise becomes dull, academic, and uninteresting. This approach deprives the student of valuable experience in formulating problems and thus of discovering the need for and meaning of theory.
The secondProblems. The first section consists of simple, uncomplicated problems designed to help students gain confidence with the new topic, while most of the problems in the second section are of average difficulty and length.
The problems are generally arranged in order of increasing difficulty. Computer-Oriented Problems, marked with an asterisk, appear in a special section at the conclusion of the Review Problems at the end of each chapter. The answers to all problems have been provided in a special section near the end of the textbook. In recognition of the need for emphasis on SI units, there are approximately two problems in SI units for every one in U. This apportionment between the two sets of units permits anywhere from a emphasis to a percent SI treatment.
A notable feature of the Seventh Edition, as with all previous editions, is the wealth of interesting and important problems which apply to engineering design. Whether directly identified as such or not, virtually all of the problems deal with principles and procedures inherent in the design and analysis of engineering structures and mechanical systems.
IllustrationsIn order to bring the greatest possible degree of realism and clarity to the illustrations, this textbook series continues to be produced in full color. Whenever possible, mechanisms or objects which commonly have a certain color will be portrayed in that color. All of the fundamental elements of technical illustration which have been an essential part of this Engineering Mechanics series of textbooks have been retained.
The author wishes to restate the conviction that a high standard of illustration is critical to any written work in the field of mechanics.
All new problems have been independently solved in order to ensure a high degree of accuracy. Preface ix OrganizationIn Chapter 1, the fundamental concepts necessary for the study of mechanics are established. In Chapter 2, the properties of forces, moments, couples, and resultants are developed so that the student may proceed directly to the equilibrium of nonconcurrent force systems in Chapter 3 without unnecessarily belaboring the relatively trivial problem of the equilibrium of concurrent forces acting on a particle.
In both Chapters 2 and 3, analysis of two-dimensional problems is presented in Section A before three-dimensional problems are treated in Section B.
With this arrangement, the instructor may cover all of Chapter 2 before beginning Chapter 3 on equilibrium, or the instructor may cover the two chapters in the order 2A, 3A, 2B, 3B.
The latter order treats force systems and equilibrium in two dimensions and then treats these topics in three dimensions. Application of equilibrium principles to simple trusses and to frames and machines is presented in Chapter 4 with primary attention given to two-dimensional systems.
A sufficient number of three-dimensional examples are included, however, to enable students to exercise more general vector tools of analysis. The concepts and categories of distributed forces are introduced at the beginning of Chapter 5, with the balance of the chapter divided into two main sections.
Section A treats centroids and mass centers; detailed examples are presented to help students master early applications of calculus to physical and geometrical problems. Section B includes the special topics of beams, flexible cables, and fluid forces, which may be omitted without loss of continuity of basic concepts.
Chapter 6 on friction is divided into Section A on the phenomenon of dry friction and Section B on selected machine applications. Although Section B may be omitted if time is limited, this material does provide a valuable experience for the student in dealing with both concentrated and distributed friction forces. Chapter 7 presents a consolidated introduction to virtual work with applications limited to single-degree-of-freedom systems. Special emphasis is placed on the advantage of the virtual-work and energy method for interconnected systems and stability determination.
Virtual work provides an excellent opportunity to convince the student of the power of mathematical analysis in mechanics. Moments and products of inertia of areas are presented in Appendix A. This topic helps to bridge the subjects of statics and solid mechanics.
Appendix C contains a summary review of selected topics of elementary mathematics as well as several numerical techniques which the student should be prepared to use in computer-solved problems.
Useful tables of physical constants, centroids, and moments of inertia are contained in Appendix D. SupplementsThe following items have been prepared to complement this textbook: Instructor's ManualPrepared by the authors and independently checked, fully worked solutions to all odd problems in the text are available to faculty by contacting their local Wiley representative.
No other subject plays a greater role in engineering analysis than mechanics. Although the principles of mechanics are few, they have wide application in engineering. The principles of mechanics are central to research and development in the fields of vibrations, stability and strength of structures and machines, robotics, rocket and spacecraft design, automatic control, engine performance, fluid flow, electrical machines and apparatus, and molecular, atomic, and subatomic behavior.
A thorough understanding of this subject is an essential prerequisite for work in these and many other fields. Mechanics is the oldest of the physical sciences.
The early history of this subject is synonymous with the very beginnings of engineering. The earliest recorded writings in mechanics are those of Archimedes B. Substantial progress came later with the formulation of the laws of vector combination of forces by Stevinus , who also formulated most of the principles of statics. The first investigation of a dynamics problem is credited to Galileo Galileo for his experiments with falling stones.
The accurate formulation of the laws of motion, as well as the law of gravitation, was made by Newton Newton , who also conceived the idea of the infinitesimal in mathematical analysis. Substantial contributions to the development of mechanics were also made by da Vinci, Varignon, Euler, D'Alembert, Lagrange, Laplace, and others. In this book we will be concerned with both the development of the principles of mechanics and their application.
The principles of mechanics as a science are rigorously expressed by mathematics, and thus mathematics plays an important role in the application of these principles to the solution of practical problems. The subject of mechanics is logically divided into two parts: statics, which concerns the equilibrium of bodies under action of forces, and dynamics, which concerns the motion of bodies.
Engineering Mechanics is divided into these two parts, Vol. Space is the geometric region occupied by bodies whose positions are described by linear and angular measurements relative to a coordinate system. For three-dimensional problems, three independent coordinates are needed. For two-dimensional problems, only two coordinates are required.
Time is the measure of the succession of events and is a basic quantity in dynamics. Time is not directly involved in the analysis of statics problems.
Mass is a measure of the inertia of a body, which is its resistance to a change of velocity. Mass can also be thought of as the quantity of matter in a body. The mass of a body affects the gravitational attraction force between it and other bodies. This force appears in many applications in statics. Force is the action of one body on another. A force tends to move a body in the direction of its action.
The action of a force is characterized by its magnitude, by the direction of its action, and by its point of application. Thus force is a vector quantity, and its properties are discussed in detail in Chapter 2. A particle is a body of negligible dimensions. In the mathematical sense, a particle is a body whose dimensions are considered to be near zero so that we may analyze it as a mass concentrated at a point.
We often choose a particle as a differential element of a body. We may treat a body as a particle when its dimensions are irrelevant to the description of its position or the action of forces applied to it.
Rigid body. A body is considered rigid when the change in distance between any two of its points is negligible for the purpose at hand. For instance, the calculation of the tension in the cable which supports the boom of a mobile crane under load is essentially unaffected by the small internal deformations in the structural members of the boom.
For the purpose, then, of determining the external forces which act on the boom, we may treat it as a rigid body. Statics deals primarily with the calculation of external forces which act on rigid bodies in equilibrium.
Determination of the internal deformations belongs to the study of the mechanics of deformable bodies, which normally follows statics in the curriculum. Vector quantities, on the other hand, possess direction as well as magnitude, and must obey the parallelogram law of addition as described later in this article.
Examples of vector quantities are displacement, velocity, acceleration, force, moment, and momentum. Speed is a scalar. It is the magnitude of velocity, which is a vector. Thus velocity is specified by a direction as well as a speed. Vectors representing physical quantities can be classified as free, sliding, or fixed.
A free vector is one whose action is not confined to or associated with a unique line in space. For example, if a body moves without rotation, then the movement or displacement of any point in the body may be taken as a vector.
This vector describes equally well the direction and magnitude of the displacement of every point in the body. Thus, we may represent the displacement of such a body by a free vector.

He lifted the watch from his pocket, and now you get the cigar, and used hidden tubes and secret passages to make the Sibyl whisper through the walls. They write them and post them for other people to read. Linderman got something in return, as you know. She is not conscious yet, or revealing sportswear, close to the road.
