Mechanics of Materials, 8e, is intended for undergraduate Mechanics of Materials courses in Mechanical, Civil, and Aerospace Engineering departments. It also serves as a useful reference for engineering students and professionals.
Containing Hibbeler’s hallmark reader-oriented features, this text is in four-color with a photorealistic art program designed to help readers visualize difficult concepts. A clear, concise writing style and more examples than any other text further contribute to readers’ ability to master the material.
Organization and Approach. In order to aid both the instructor and the student, the contents of each chapter are organized into well-defined sections. Selected groups of sections contain an explanation of specific topics, followed by illustrative example problems and a set of homework problems. The topics within each section are often placed in subgroups denoted by boldface titles. The purpose of this is to present a structured method for introducing each new definition or concept and to make the book convenient for later reference and review. Furthermore, important terms in the chapter have been highlighted in boldface to provide a convenient means for review.
Chapter Contents. Each chapter begins with a photo to illustrate a broad range application of the material within the chapter. The "chapter objectives" are then provided to give a general overview of the material that will be covered.
Procedures for Analysis. Found in many sections of the book, this unique feature provides the student with a logical and orderly method to follow when applying the theory. The example problems are then solved using this outlined method in order to clarify its numerical application. It is to be understood, however, that once the relevant principles have been mastered and enough confidence and judgment have been acquired, the student can then develop his or her own procedures for solving problems.
Important Points. This feature provides a review or summary of the most important concepts in a section and highlights the most significant points that should be realized when applying the theory to solve problems.
Conceptual Understanding. Through the use of photographs placed throughout the book, examples of the theory are provided in order to illustrate some of its more important conceptual features and instill the physical meaning of many of the terms used in the equations.
Example Problems. All the example problems are presented in a concise manner and in a style that is easy to understand. New examples have been added throughout the text, and some from the previous edition have been shortened.
Homework Problems. Numerous problems in the book depict realistic situations encountered in engineering practice. It is hoped that this realism will both stimulate the student's interest in the subject and provide a means for developing the skill to reduce any such problem from its physical description to a model or symbolic representation to which the principles may be applied.
Throughout the book there is an approximate balance of problems using either SI or FPS units. Furthermore, in any set, an attempt has been made to arrange the problems in order of increasing difficulty. The answers to all but every fourth problem are listed in the back of the book. To alert the user to a problem without a reported answer, an asterisk (*) is placed before the problem number. Answers are reported to three significant figures, even though the data for material properties may be known with less accuracy. Although this might appear to be poor practice, it is done simply to be consistent and to allow the student a better chance to validate his or her solution. All the problems and their solutions have been independently checked for accuracy. A solid square is used to identify problems that require a numerical analysis or computer application.
Appendices. The appendices of the book provide a source for review and a listing of tabular data. Appendix A provides information on the centroid and the moment of inertia of an area. Appendices B and C list tabular data for structural shapes, and the deflection and slopes of various types of beams and shafts. Appendix D, which is titled "Review for the Fundamentals of Engineering Exam," contains typical problems, along with their partial solutions, that are commonly used on FE exams. These problems may also be used for review and practice in preparing for class examinations.
Accuracy Checking. The edition has undergone rigorous accuracy checking and proofing of pages. Besides the author's review of all art pieces and pages, Karim Nohra of the University of South Florida and Scott Hendricks of Virginia Polytechnic Institute rechecked the page proofs twice, and together reviewed the entire Solutions Manual.
Supplements. Several instructor's supplements are available with this text. An instructor's solutions manual was prepared and typeset by the author. It has been completely checked for accuracy. In addition, an Instructor's Resource CD is available containing PowerPoint slides and pdf files of text art, as well as PowerPoint slides of text examples.
