Thus, the engineering mechanics sequence is critical to the engineering curriculum. In addition, these courses serve as excellent settings in which to strengthen problem-solving abilities.

Philosophy The primary purpose of the study of engineering mechanics is to develop the capacity to predict the effects of force and motion while carrying out the creative design functions of engineering. One of the primary objectives in a mechan- ics 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 prob- lems.

This approach deprives the student of valuable experience in formulating problems and thus of discovering the need for and meaning of theory. The second view pro- vides by far the stronger motive for learning theory and leads to a better balance between theory and application. The crucial role played by interest and purpose in providing the strongest possible motive for learning cannot be overemphasized.

Furthermore, as mechanics educators, we should stress the understanding that, at best, theory can only approximate the real world of mechanics rather than the view that the real world approximates the theory.

This difference in philosophy is indeed basic and distinguishes the engineering of mechanics from the science of mechanics. Over the past several decades, several unfortunate tendencies have occurred in engineer- ing education. First, emphasis on the geometric and physical meanings of prerequisite mathe- matics appears to have diminished.

Third, in advancing the mathematical level of our treat- ment of mechanics, there has been a tendency to allow the notational manipulation of vector operations to mask or replace geometric visualization. Mechanics is inherently a subject which depends on geometric and physical perception, and we should increase our efforts to develop this ability.

A special note on the use of computers is in order. The experience of formulating problems, where reason and judgment are developed, is vastly more important for the student than is the manipulative exercise in carrying out the solution. For this reason, computer usage must be carefully controlled.

At present, constructing free-body diagrams and formulating governing equations are best done with pencil and paper. On the other hand, there are instances in which the solution to the governing equations can best be carried out and displayed using the com- puter. These thoughts have been kept in mind during the design of the computer-oriented problems in the Seventh Edition. To conserve adequate time for problem formulation, it is suggested that the student be assigned only a limited number of the computer-oriented problems.

As with previous editions, this Seventh Edition of Engineering Mechanics is written with the foregoing philosophy in mind. Engineering Mechanics is written in a style which is both concise and friendly. The major emphasis is on basic principles and methods rather than on a multitude of special cases. Strong effort has been made to show both the cohesiveness of the relatively few fundamental ideas and the great variety of prob- lems which these few ideas will solve.

Pedagogical Features The basic structure of this textbook consists of an article which rigorously treats the par- ticular subject matter at hand, followed by one or more Sample Problems, followed by a group of Problems. There is a Chapter Review at the end of each chapter which summarizes the main points in that chapter, followed by a Review Problem set. Problems The sample problems appear on specially colored pages by themselves. The solu- tions to typical dynamics problems are presented in detail.

In addition, explanatory and cautionary notes Helpful Hints in blue type are number-keyed to the main presentation. There are homework exercises, of which approximately 45 percent are new to the Seventh Edition.

The problem sets are divided into Introductory Problems and Representa- tive Problems. 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 at the end of the textbook. In recognition of the need for emphasis on SI units, there are approximately two prob- lems in SI units for every one in U.

This apportionment between the two sets of units permits anywhere from a 50—50 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. Illustrations In 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 cer- tain color will be portrayed in that color. All of the fundamental elements of technical illus- tration which have been an essential part of this Engineering Mechanics series of textbooks have been retained. Special Features While retaining the hallmark features of all previous editions, we have incorporated these improvements: These diagrams are well integrated with the time-order form of the impulse-momentum equations.

All new problems have been independently solved in order to ensure a high degree of accuracy. Preface ix 9. Organization The logical division between particle dynamics Part I and rigid-body dynamics Part II has been preserved, with each part treating the kinematics prior to the kinetics.

In Chapter 1, the fundamental concepts necessary for the study of dynamics are established. Chapter 2 treats the kinematics of particle motion in various coordinate systems, as well as the subjects of relative and constrained motion.

Chapter 3 on particle kinetics focuses on the three basic methods: The special topics of impact, central-force motion, and relative motion are grouped together in a special applications section Section D and serve as optional material to be assigned according to instructor preference and available time. With this arrangement, the attention of the stu- dent is focused more strongly on the three basic approaches to kinetics.

Chapter 4 on systems of particles is an extension of the principles of motion for a single particle and develops the general relationships which are so basic to the modern compre- hension of dynamics. In Chapter 5 on the kinematics of rigid bodies in plane motion, where the equations of relative velocity and relative acceleration are encountered, emphasis is placed jointly on solution by vector geometry and solution by vector algebra. This dual approach serves to reinforce the meaning of vector mathematics.

In Chapter 6 on the kinetics of rigid bodies, we place great emphasis on the basic equations which govern all categories of plane motion.

Special emphasis is also placed on forming the direct equivalence between the actual applied forces and couples and their and resultants. In this way the versatility of the moment principle is em- phasized, and the student is encouraged to think directly in terms of resultant dynamics effects.

For students who later pursue more advanced work in dynamics, Chapter 7 will provide a solid foundation. Gyroscopic motion with steady precession is treated in two ways. With this treatment, the student can understand the gyroscopic phenomenon of steady precession and can handle most of the engineering problems on gyroscopes without a detailed study of three-dimensional dynamics.

The second approach employs the more general momentum equations for three-dimensional rotation where all components of momentum are ac- counted for. Chapter 8 is devoted to the topic of vibrations. This full-chapter coverage will be espe- cially useful for engineering students whose only exposure to vibrations is acquired in the basic dynamics course.

Moments and products of inertia of mass are presented in Appendix B. Appendix C con- tains a summary review of selected topics of elementary mathematics as well as several nu- merical techniques which the student should be prepared to use in computer-solved problems. Useful tables of physical constants, centroids, and moments of inertia are con- tained in Appendix D.

The study of dynamics in engineer- ing usually follows the study of statics, which deals with the effects of forces on bodies at rest. Dynamics has two distinct parts: A thorough comprehension of dynamics will provide one of the most useful and powerful tools for analysis in engineering.

History of Dynamics Dynamics is a relatively recent subject compared with statics. The beginning of a rational understanding of dynamics is credited to Galileo — , who made careful observations concerning bodies in free fall, motion on an inclined plane, and motion of the pendulum.

Galileo was continually under severe criticism for refusing to accept the established beliefs of his day, such as the philoso- phies of Aristotle which held, for example, that heavy bodies fall more rapidly than light bodies.

Although his mathe- matical description was accurate, he felt that the concept of remote transmission of gravitational force without a supporting medium was an absurd notion. Applications of Dynamics Only since machines and structures have operated with high speeds and appreciable accelerations has it been necessary to make calculations based on the principles of dynamics rather than on the principles of statics. The rapid technological developments of the present day require increasing application of the principles of mechanics, particularly dy- namics.

Students with interests in one or more of these and many other activities will constantly need to apply the fundamental principles of dynamics. They are summarized here along with additional comments of special relevance to the study of dynamics.

Space is the geometric region occupied by bodies. Position in space is determined relative to some geometric reference system by means of linear and angular measurements. The basic frame of reference for the laws of Newtonian mechanics is the primary inertial system or astro- nomical frame of reference, which is an imaginary set of rectangular axes assumed to have no translation or rotation in space. Cajori, University of California Press, For most engineering problems involving machines and structures which remain on the surface of the earth, the corrections are extremely small and may be neglected.

For these problems the laws of mechanics may be applied directly with mea- surements made relative to the earth, and in a practical sense such mea- surements will be considered absolute. Time is a measure of the succession of events and is considered an absolute quantity in Newtonian mechanics.

Mass is the quantitative measure of the inertia or resistance to change in motion of a body. Mass may also be considered as the quantity of matter in a body as well as the property which gives rise to gravita- tional attraction.

Force is the vector action of one body on another. The properties of forces have been thoroughly treated in Vol. A particle is a body of negligible dimensions. When the dimensions of a body are irrelevant to the description of its motion or the action of forces on it, the body may be treated as a particle. A rigid body is a body whose changes in shape are negligible com- pared with the overall dimensions of the body or with the changes in po- sition of the body as a whole.

For this purpose, then, the treatment of the airplane as a rigid body is an accept- able approximation. On the other hand, if we need to examine the inter- nal stresses in the wing structure due to changing dynamic loads, then the deformation characteristics of the structure would have to be exam- ined, and for this purpose the airplane could no longer be considered a rigid body.

Vector and scalar quantities have been treated extensively in Vol. Scalar quantities are printed in lightface italic type, and vectors are shown in boldface type. Thus, V denotes the scalar magnitude of the vector V.

It is important that we use an identifying mark, such as an underline V, for all handwritten vectors to take the place of the boldface designation in print. We assume that you are familiar with the geometry and algebra of vectors through previous study of statics and mathematics. Mechanics by its very na- ture is geometrical, and students should bear this in mind as they review their mathematics.

In addition to vector algebra, dynamics re- quires the use of vector calculus, and the essentials of this topic will be developed in the text as they are needed. Dynamics involves the frequent use of time derivatives of both vec- tors and scalars. As a notational shorthand, a dot over a symbol will fre- quently be used to indicate a derivative with respect to time.

In modern terminology they are: Law I. A particle remains at rest or continues to move with uniform velocity in a straight line with a constant speed if there is no unbal- anced force acting on it. Law II. The acceleration of a particle is proportional to the resul- tant force acting on it and is in the direction of this force. The forces of action and reaction between interacting bod- ies are equal in magnitude, opposite in direction, and collinear. The third law constitutes the principle of action and reaction with which you should be thoroughly familiar from your work in statics.

However, numerical conversion from one system to the other will often be needed in U. Both formulations are equally correct when applied to a particle of constant mass. To become familiar with each system, it is necessary to think directly in that system. Notify me of new posts by email. Leave this field empty.
