Our original objective in writing this book was to present the foundations and applications of dynamics 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. With encouragement and help from many students and fellow teachers who have used the book, we continue and expand upon these themes in this edition.

Examples that Teach

The Strategy/Solution/Discussion framework employed in 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.

Engineering Design

We include simple design considerations in many examples and problems without compromising emphasis on fundamental mechanics. Design problems are marked with a D icon. Optional examples titled "Application to Engineering" provide more detailed discussions of the uses of dynamics in engineering design.

Computational Mechanics

Some instructors prefer to teach dynamics without requiring the use of a computer. Others use dynamics as an opportunity to introduce students to the use of computers in engineering, having them either write their own programs in a lower level language or use higher level problem-solving software. Our book is suitable for each of these approaches. We provide optional, self-contained "Computational Mechanics" sections with examples and problems designed for solution by a programmable calculator or computer. In addition, tutorials on using Mathcad® and MATLAB® in engineering mechanics are available from our text's website. See Supplements (page xv) for a further description.

Consistent Use of Color

To help students recognize and interpret elements of figures, we use consistent identifying colors.

New to the Third Edition

Positive responses from users and reviewers have led us to retain the basic organization, content, and features of the first edition. During our preparation of this edition, 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. In response to requests, we made the following notable changes:

• Problems that contain elements of engineering design have been marked with a new D icon.
• 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.
• We provide over 300 new and revised problems, including the conversion of some problems from U.S. Customary to SI units. As with the examples, many of the new problems continue our focus on applications of dynamics within the context of engineering practice.
• New sets of Study Questions appear after most sections to help students check their retention of key concepts.
• Each example is clearly labeled for its teaching purpose.
• We have redesigned the text and also added photographs throughout to help students relate the text to actual applications and situations.
• An extensive new supplement program includes web-based assessment software, visualization software, and much more. See the Supplements description for complete information.
• At the suggestion of reviewers, we have improved the organization of Chapter 20 by introducing Eider's equations earlier and moving the material on moments and products of inertia to an appendix at the end of the chapter.

Commitment to Students and Instructors

In revising the textbook and 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.

Supplements

Student Supplements

Web Assessment Software lets students solve problems from the text with randomized variables so each student solves a slightly different problem. After students have submitted their answers, they receive the correct answers and, if necessary, can continue to attempt similar problems until they are successful. By integrating with an optional course management system, professors can have student results recorded electronically. Students may also print random problem sets for submission and traditional grading. Contact your Prentice Hall representative for more information and for instructor's passwords. This site is password protected—student passwords appear in each text's accompanying Dynamics Study Pack.

Dynamics Study Pack is designed to give students the tools to improve their study skills. The Dynamics Study Pack comes bundled at no additional cost with every Third Edition of Dynamics sold in bookstores. It consists of three study components—a free body-diagram workbook, a Visualization CD based on Working Model Software, and an access code to a website with 500 sample Statics and Dynamics problems and solutions.

• Free-Body Diagram Workbook prepared by Peter Schiavone of the University of Alberta. This workbook begins with a tutorial on free body diagrams and then includes 50 practice problems of progressing difficulty with complete solutions. Further "strategies and tips" help students understand how to use the diagrams in solving the accompanying problems.
• Working Model CD contains 28 pre-set simulations of Dynamics examples in the text that include questions for further exploration. Simulations are powered by the Working Model Engine and were created with actual artwork from the text to enhance their correlation with the text.
• Password-Protected Website contains 500 sample Statics and Dynamics problems for students to study. Problems are keyed to each chapter of the text and contain complete solutions. All problems are supplemental and do not appear in the Third Edition. Student passwords are printed on the inside cover of the Free-Body Diagram Workbook.
