The Eighth Edition of MECHANICS OF MATERIALS continues its tradition as one of the leading texts on the market. With its hallmark clarity and accuracy, this text develops student understanding along with analytical and problem-solving skills. The main topics include analysis and design of structural members subjected to tension, compression, torsion, bending, and more. The book includes more material than can be taught in a single course giving instructors the opportunity to select the topics they wish to cover while leaving any remaining material as a valuable student reference.
- Learning objectives have been added to the beginning of each chapter.
- Chapter Overview sections have been updated with all important concepts highlighted.
- Updated Chapter Summary and Review sections at the end of each chapter now include key formulas derived, discussed and applied to problem solutions.
- An enhanced step-by-step solution approach has been implemented so that important fundamental concepts can be highlighted and emphasized.
- Over 100 new problems typical in type and format of those found on the FE Examination have been added in an additional appendix to assist students in preparing for the FE Exam.
- All problems have been reviewed for appropriateness and accuracy; many were revised or updated to improve clarity in presentation of fundamental concepts; in some cases, problem solutions were revised to enhance learning.
- New section added to Chapter 1 to assist the student in making the transition from the prerequisite course on Statics to Mechanics of Materials; fundamental concepts of equilibrium are reviewed and then applied to solution of sample problems like those they will encounter in later chapters.
- Clarity and accuracy: Considerable effort was spent in designing, checking, and proofreading the text and figures.
- Problems: The text offers more than 1000 problems for homework assignments and classroom discussions. The exercises are arranged in order of difficulty and placed at the end of the chapter making them easy to find without breaking up the subject matter.
- Examples: Numerous examples illustrate the theoretical concepts and show how those concepts may be used in practical situations. In some cases, photographs have been added showing actual engineering structures or components to reinforce the tie between theory and application.
- Both the International System of Units (SI) and the U.S. Customary System (USCS) are used in the examples and problems allowing students to gain proficiency using both.
- 4-color format provides better visualization of graphs and worked out problems.

"The authors do and excellent job of discussing the topics at a level I believe will be absorbed by the students. They also make a good effort to highlight the important issues and points in the text by italicizing or bolding. I feel that the author has done an excellent job of relating real structures to solid body analysis techniques, and haspresented and discussed it in a manner that I think students will appreciate."
"The homework problems are perhaps the strongest point of the text. The problems cover the waterfront in variety, complexity and coverage. They include numerous examples that are found inthe real world and students can identify with them."
"The books strongest feature is the comprehensive coverage and reasonableness of the homework problems in establishing a base of understanding of expected levels of stress, strain, and displacement."
"The author has done an excellent job conveying the concepts. The textbook is easy to follow and all the ideas are clearly presented."
"This is a detailed overview of undergraduate solid mechanics. It is an excellent book, and far superior to current texts, which borrowed extensively from Gere."
