The main objective of a first course in mechanics should be to develop in the engineering student the ability to analyze any problem in a simple and logical manner and to apply to its solution a few, well-understood, basic principles. This text is designed to help the instructor achieve this goal.
Vector analysis is introduced early in the text and is used in the presentation and discussion of the fundamental principles of mechanics. Vector methods are also used to solve many problems, particularly three-dimensional problems where these techniques result in a simpler and more concise solution. The emphasis in this text, however, remains on the correct understanding of the principles of mechanics and on their application to the solution of engineering problems, and vector analysis is presented chiefly as a convenient tool.
In order to achieve the goal of being able to analyze mechanics problems, the text employs the following pedagogical strategy:
Practical applications are introduced early.
New concepts are introduced simply.
Fundamental principles are placed in simple contexts.
Students are given extensive practice through:
special sections entitled Solving Problems on Your Own,
extensive homework problem sets,
review problems at the end of each chapter, and
computer problems designed to be solved with computational software.
Concept Questions, multiple-choice problems that require few, if any, calculations, are included. Students are encouraged to solve these problems using the principles and techniques discussed in the text and to use these principles to help develop their intuition.
Thoroughly Refreshed Problem Set in the Tenth Edition. Seventy per cent of the problems are updated from the previous edition.
Well-Respected Sample Problems are a signature Beer and Johnston text feature that allow students to see important key problem types and with the solution laid out on a single page, organized to provide a potent model for student problem-solving. Sample Problems serve the dual purpose of amplifying the text and demonstrating the type of neat and orderly work that students should cultivate in their own solutions.
Instructor's and Solutions Manual offers a clear typeset presentation and organization of problem solutions. In addition, instructors are provided with assignment grids, designed so that instructors can assign different homework problems each semester for up to six semesters. Also included is a description of the material covered in each chapter and hints to help instructors assign appropriate homework problems.
Computer and Design Problems are offered at the end of each chapter. While the problems are generic they are designed to be easily solved using popular computational programs like MatlabR, MathcadR, and Maple™. The computer problems focus on symbolic manipulation and plotting rather than programming.
Connect Engineering provides a large selection of algorithmically generated exercises that feature hints, guided solutions, and more. Additionally, ConnectPlus offers an integrated e-book.
A Careful, Step-By-Step Presentation is followed in each lesson of each chapter, and every chapter starts with a real-life example and an outline previewing the chapter objectives and lessons. Each lesson is accompanied by sample problems and Solving Problems on Your Own boxes that prepare students for the problem sets. Each chapter finishes with a brief Review Problem set and an assortment of computer and design problems.

Ferdinand P. Beer. Born in France and educated in France and Switzerland, Ferd received an M.S. degree from the Sorbonne and an Sc.D. degree in theoretical mechanics from the University of Geneva. He came to the United States after serving in the French army during the early part of World War II and taught for four years at Williams College in the Williams-MIT joint arts and engineering program. Following his service at Williams College, Ferd joined the faculty of Lehigh University where he taught for thirty-seven years. He held several positions, including University Distinguished Professor and chairman of the Department of Mechanical Engineering and Mechanics, and in 1995 Ferd was awarded an honorary Doctor of Engineering degree by Lehigh University.
E. Russell Johnston, Jr. Born in Philadelphia, Russ holds a B.S. degree in civil engineering from the University of Delaware and an Sc.D. degree in the field of structural engineering from the Massachusetts Institute of Technology. He taught at Lehigh University and Worcester Polytechnic Institute before joining the faculty of the University of Connecticut where he held the position of chairman of the Department of Civil Engineering and taught for twenty-six years. In 1991 Russ received the Outstanding Civil Engineer Award from the Connecticut Section of the American Society of Civil Engineers.
David F. Mazurek. David holds a B.S. degree in ocean engineering and an M.S. degree in civil engineering from the Florida Institute of Technology and a Ph.D. degree in civil engineering from the University of Connecticut. He was employed by the Electric Boat Division of General Dynamics Corporation and taught at Lafayette College prior to joining the U.S. Coast Guard Academy, where he has been since 1990. He has served on the American Railway Engineering & Maintenance-of-Way Association’s Committee 15—Steel Structures since 1991. Professional interests include bridge engineering, structural forensics, and blast-resistant design. He is a registered Professional Engineer in Connecticut and Pennsylvania.
Beer and Johnston’s collaboration has spanned more than half a century and many successful revisions of all of their textbooks, and their contributions to engineering education have earned them a number of honors and awards. They were presented with the Western Electric Fund Award for excellence in the instruction of engineering students by their respective regional sections of the American Society for Engineering Education, and they both received the Distinguished Educator Award from the Mechanics Division of the same society. Starting in 2001, the New Mechanics Educator Award of the Mechanics Division has been named in honor of the Beer and Johnston author team.
