1.Description
In his substantial revision of Engineering Mechanics, R.C. Hibbeler
empowers students to succeed in the whole learning experience. Hibbeler
achieves this by calling on his everyday classroom experience and his
knowledge of how students learn inside and outside of lecture.

In addition to over 50% new homework problems, the twelfth edition
introduces the new elements of Conceptual Problems, Fundamental Problems
and MasteringEngineering, the most technologically advanced online
tutorial and homework system.

2.Features

Problem Solving

R.C. Hibbeler’s text features a large variety of problem types from a
broad range of engineering disciplines, stressing practical, realistic
situations encountered in professional practice, varying levels of
difficulty, and problems that involve solution by computer.

(NEW) Fundamental Problems. 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.

(NEW) Conceptual Problems. 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.

Procedures for Analysis. 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.

Examples. Designed to help students who “learn by example”, R.C.
Hibbeler’s Examples illustrate the application of fundamental theory to
practical engineering problems and reflect problem solving strategies
discussed in associated Procedures for Analysis.

Important Points. 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.

Emphasis on Free-Body Diagrams. 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.

General Analysis and Design Problems. 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. It is
hoped that this realism will both stimulate the student’s interest in
engineering mechanics and provide a means for developing the skill to
reduce any such problem from its physical description to a model or
symbolic representation to which the principles of mechanics may be
applied.

Student Study Pack. 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 — ۷۵ pages that step students
through numerous free body diagram problems. Full explanations and
solutions are provided.

Statics Practice Problem Workbook. This workbook contains additional
worked problems. The problems are partially solved and are designed to
help guide students through difficult topics.

Visualization

PhotoRealistic Art — ۳D figures rendered with photographic quality

Photographs. Many photographs are used throughout the book to explain
how the principles of mechanics apply to real-world situation. 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.

Illustrations. These figures provide a strong connection to the 3-D
nature of engineering. Particular attention has also been paid to
providing a view of any physical object, its dimensions, and the vectors
in a manner that can be easily understood.

Review and Student Support

End of Chapter Review. A thorough end of chapter review includes each
important point accompanied by the relevant equation and art from the
chapter providing the students a concise tool for reviewing chapter
contents.

(NEW) MasteringEngineering. The most technologically advanced online
tutorial and homework system. MasteringEngineering is designed to
provide students with customized coaching and individualized feedback to
help improve problem-solving skills while providing instructors with
rich teaching diagnostics.

(NEW) Video Solutions. Developed by Professor Edward Berger, University
of Virginia, video solutions are located on the Companion Website for
the text and offer step-by-step solution walkthroughs of representative
homework problems from each section of the text.

Student Study Pack. 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 — ۷۵ pages that step students
through numerous free body diagram problems. Full explanations and
solutions are provided.

Statics Practice Problem Workbook. This workbook contains additional
worked problems. The problems are partially solved and are designed to
help guide students through difficult topics.

Accuracy

As with the previous editions, apart from the author, the accuracy of
the text and problem solutions has been thoroughly checked by four other
parties: Scott Hendricks, Virginia Polytechnic Institute and State
University; Karim Nohra, University of South Florida; Kurt Norlin,
Laurel Tech Integrated Publishing Services; and finally Kai Beng, a
practicing engineer, who in addition to accuracy review provided content
development suggestions.

3.New To This Edition

New Problems. There are new problems added to this edition including
aerospace and petroleum engineering, and biomechanics applications.

Fundamental Problems. 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.

Conceptual Problems. 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.

Additional Photos. The relevance of knowing the subject matter is
reflected by the real world applications depicted in over 60 new and
updated photos placed throughout the book. These photos are generally
used to explain how the principles of mechanics apply to real-world
situations. In some sections, 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.

Content Revisions. Each section of the text was carefully reviewed and,
in many areas, the material has been redeveloped to better explain the
concepts.

MasteringEngineering. The most technologically advanced online tutorial
and homework system. MasteringEngineering is designed to provide
students with customized coaching and individualized feedback to help
improve problem-solving skills while providing instructors with rich
teaching diagnostics.

Video Solutions. Developed by Professor Edward Berger, University of
Virginia, video solutions are located on the Companion Website for the
text and offer step-by-step solution walkthroughs of representative
homework problems from each section of the text. The videos are designed
to be a flexible resource to be used however each instructor and
student prefers.
