PREFACE It is intended that this book provide the student with a clear and thorough presentation of the theory and application of the principles of mechanics of materials. To achieve this objective, over the years this work has been shaped by the comments and suggestions of hundreds of reviewers in the teaching profession, as well as many of the author’s students. The tenth edition has been significantly enhanced from the previous edition, and it is hoped that both the instructor and student will benefit greatly from these improvements. NEW TO THIS EDITION • Updated Material. Many topics in the book have been re-written in order to further enhance clarity and to be more succinct. Also, some of the artwork has been enlarged and improved throughout the book to support these changes. • New Layout Design. Additional design features have been added to this edition to provide a better display of the material. Almost all the topics are presented on a one or two page spread so that page turning is minimized. • Improved Preliminary and Fundamental Problems. These problems sets are located just after each group of example problems. They offer students basic applications of the concepts covered in each section, and they help provide the chance to develop their problem-solving skills before attempting to solve any of the standard problems that follow. The problems sets may be considered as extended examples, since in this edition their complete solutions are given in the back of the book. Additionally, when assigned, these problems offer students an excellent means of preparing for exams, and they can be used at a later time as a review when studying for the Fundamentals of Engineering Exam. • New Photos. The relevance of knowing the subject matter is reflected by the real-world application of the 14 new or updated photos placed throughout the book. These photos generally are used to explain how the principles apply to real-world situations and how materials behave under load
