Description In his revision of Engineering Mechanics , R. Series This product is part of the following series. MasteringEngineering Series.

Preface Preface is available for download in PDF format. Problem Solving R. These problem sets follow the example problems. They offer students simple applications of the concepts and, therefore, provide them with the chance to develop their problem-solving skills before attempting to solve any of the standard problems that follow. You may consider these problems as extended examples since they all have partial solutions and answers that are given in the back of the book.

Throughout the text, usually at the end of each chapter, there is a set of problems that involve conceptual situations related to the application of the mechanics principles contained in the chapter.

These analysis and design problems are intended to engage the students in thinking through a real-life situation as depicted in a photo. This feature provides students with a logical and orderly method for applying theory and building problem solving skills.

A general procedure for analyzing any mechanical problem is presented at the end of the first chapter. Then this procedure is customized to relate to specific types of problems that are covered throughout the book.

This feature provides a review or summary of the most important concepts in a section and highlights the most significant points that should be realized when applying the theory to solve problems. Drawing a free-body diagram is particularly important when solving problems, and for this reason this step is strongly emphasized throughout the book. In particular, special sections and examples are devoted to show how to draw free-body diagrams. Specific homework problems have also been added to develop this practice.

The majority of problems in the book depict realistic situations encountered in engineering practice. Some of these problems come from actual products used in industry. This supplement contains chapter-by-chapter study materials, a Free-Body Diagram Workbook and access to the Companion Website.

Part I - A chapter-by-chapter review including key points, equations, and check up questions. Part II - Free Body Diagram workbook — 75 pages that step students through numerous free body diagram problems. Full explanations and solutions are provided.

Access Code - www. In some section, photographs have been used to show how engineers must first make an idealized model for analysis and then proceed to draw a free-body diagram of this model in order to apply the theory. Most photographs were taken by the author, and include appropriate vectors and notation illustrating a mechanics concept. New to This Edition. New Problems. These new problems relate to applications in many different fields of engineering. Also, a significant increase in algebraic type problems has been added, so that a generalized solution can be obtained.

Additional Fundamental Problems. These problem sets serve as extended example problems since their solutions are given in the back of the book. Additional problems have been added, especially in the areas of frames and machines, and in friction. Expanded Solutions. Some of the fundamental problems now have more detailed solutions, including some artwork, for better clarification. Also, some of the more difficult problems have additional hints along with its answer when given in the back of the book.

Updated Photos. The relevance of knowing the subject matter is reflected by the realistic applications depicted by the many photos placed throughout the book. In this edition 20 new or updated photos are included. These, along with all the others, are generally used to explain how the relevant principles of mechanics apply to real-world situations. In some sections they are incorporated into the example problems, or to show how to model then draw the free-body diagram of an actual object.

Throughout the book examples have been altered or enhanced in an attempt to help clarify concepts for students.

Where appropriate new examples have been added in order to emphasize important concepts that were needed. New Conceptual Problems. The conceptual problems given at the end of many of the problem sets are intended to engage the students in thinking through a real-life situation as depicted in a photo. They can be assigned either as individual or team projects after the students have developed some expertise in the subject matter. Share a link to All Resources.
