This book presents the foundations and applications of statics and mechanics of materials by emphasizing the importance of visual analysis of topics-especially through the use of free body diagrams. It also promotes a problem-solving approach to solving examples through its strategy, solution, and discussion format in examples. The AUTHORs further include design and computational examples that help integrate these ABET 2000 requirements. Chapter topics include vectors, forces, systems of forces and moments, objects in equilibrium, structures in equilibrium, centroids and centers of mass centroids, moments of inertia, measures of stress and strain, states of stress, states of strain and the stress-strain relations, axially loaded bars, torsion, internal forces and moments in beams, stresses in beams, deflections of beams, buckling of columns, energy methods, and introduction to fracture mechanics. For civil/aeronautical/engineering mechanics.

He is an associate editor of the journal Experimental Mechanics, published by the Society for Experimental Mechanics.

Our original objective in writing this book was to present the foundations and applications of statics and mechanics of materials as we do in the classroom. We used many sequences of figures, emulating the gradual development of a figure by a teacher explaining a concept. We stressed the importance of visual analysis in gaining understanding, especially through the use of free-body diagrams. Because inspiration is so conducive to learning, we based many of our examples and problems on a variety of modern engineering applications. Key Series Features This volume completes our series in Engineering Mechanics that includes Engineering Mechanics-Statics,Third Edition, by Bedford and Fowler Engineering Mechanics-Dynamics,Third Edition, by Bedford and Fowler Engineering Mechanics-Statics & Dynamics,Third Edition, by Bedford and Fowler Engineering Mechanics-Statics Principles,by Bedford and Fowler Engineering Mechanics-Dynamics Principles,by Bedford and Fowler Engineering Mechanics-Statics & Dynamics Principles,by Bedford and Fowler Mechanics of Materialsby Bedford and Liechti Statics and Mechanics of Materialsby Bedford, Fowler, and Liechti (this volume) Positive responses from users and reviewers have led us to retain the basic organization, content, and features. During our preparation of this volume, we examined how we presented each concept, example, figure, summary statement, and problem. Where necessary, we made changes, additions, or deletions to simplify and clarify the presentation. This volume features Problems that contain elements of engineering design have been marked with a newDicon. We have added new examples where users indicated more were needed. Many of the new examples continue our emphasis on realistic and motivational applications and engineering design. New sets ofStudy Questionsappear after most sections to help students check their retention of key concepts. Each example is clearly labeled for its teaching purpose. A redesigned text and added photographs throughout help students connect the text real world applications and situations. Examples that Teach The Strategy/Solution/Discussion framework employed by most of our examples is designed to emphasize the critical importance of good problem-solving skills. Our objective is to teach students how to approach problems and critically judge the results. Commitment to Students and Instructors In preparing this volume and the accompanying solutions manual, we have taken precautions to ensure accuracy to the best of our ability. We have each solved the new problems in an effort to be sure that their answers are correct and that they are of an appropriate level of difficulty. Karim Nohra of the University of South Florida also checked the text, examples, problems and solutions manual. Any errors that remain are the responsibility of the authors. We welcome communication from students and instructors concerning errors or areas for improvement. Our mailing address is Department of Aerospace Engineering and Engineering Mechanics, University of Texas at Austin, Austin, Texas 78712. Our electronic mail address isabedford@mail.utexas.edu. Supplements Instructor's Solutions ManualThis supplement, available to instructors contains complete solutions to all of the problems and several sample syllabi. Each solution comes with problem statement as well as associated artwork. Study Packsare designed to give students the tools to improve their mechanics study skills.
