Our original objective in writing this book was to present the foundations and applications of statics 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 statics without requiring the use of a computer. Others use statics 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 xxi) for a further description.

Consistent Use of Color

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

• Unit vectors
• Forces
• Positions
• Couples

New to the Third Edition

Positive responses from users and reviewers have led us to retain the basic organization, 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:

• 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 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 connect the text to real world 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.

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

PHGradeAssist 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 actual answers and can keep trying similar problems until they are successful. By integrating with an optional course management system, professors can have student results recorded electronically. Consult the About this Package section of this book, visit www.prenhall.com/bedford, or contact your PH sales representative for more information. Student Access Code Cards come bundled with each new copy of this text, and are also available by ordering with ISBN 0-13-0460435. Professor access codes are available through your PH sales rep or by emailing engineering@prenhall.com.

Dynamics Study Pack–This optional supplement is designed to give students the tools to improve their study skills. 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 25 pre-set simulations of Statics 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.

MATLAB® /Mathcad® Tutorials. Twenty tutorials showing how to use computational software in engineering mechanics. Each tutorial discusses a basic mechanics concept, and then shows how to solve a specific problem related to this concept using MaTLAS/Mathcad. There are twenty tutorials each for MATLAB and Mathcad, and are available in PDF format from the access codes protected area of the Bedford website. Worksheets were developed by Ronald Larsen and Stephen Hunt of Montana State University-Bowman.

Contact either your sales rep or engineering@prenhall.com for pricing and bundling options.

ADAMS Simulations for Dynamics—Mechanical Dynamics, Inc. has created over 100 simulations of problems from Dynamics using their ADAMS simulation/prototyping software. Professors and students can simulate and observe the effects of changing parameters in systems and gain deeper insight into their behavior. Simulations also come with an accompanying avi "movie" file. Files are located at the access code protected part of the website. Qualified adopters may also be able to obtain free site licenses. Contact university@adams.com for more information.

Instructor Supplements

Instructor's Solutions Manual and Presentation CD. This supplement available to instructors contains problem statements with completely worked out solutions. The problem statements correspond by chapter and number to those at the PHGradeAssist site. Professors can thus see one sample solution to each PHGA problem. The separate CD contains PowerPoint slides of art from examples and text passages, as well as pdf files of art from the book.

PHGradeAssist 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 actual answers and can keep trying similar problems until they are successful. By integrating with an optional course management system, professors can have student results recorded electronically. Consult the About this Package section of this book, visit www.prenhall.com...
