Engineering Mechanics Dynamics (12th Edition)


The main purpose of this book is to provide the student with a clear and thorough presentation of the theory and application of engineering mechanics. To achieve this objective, this work has been shaped by the comments and suggestions of hundreds of reviewers in the teaching profession, as well as many of the author’s students. The twelfth edition of this book has been significantly enhanced from the previous edition and it is hoped that both the instructor and student will benefit greatly from these improvements.

New Features

Funda mental Problems.

These problem sets are located just after 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. Additionally, the fundamental
problems offer students an excellent means of studying for exams; and they can be
used at a later time as a preparation for the Fundamentals in Engineering Exam.


Each section of the text was carefully reviewed and, in many areas, the
material has been redeveloped to better explain the concepts. This has included adding
or changing several of the examples in order to provide more emphasis on the
applications of the important concepts.

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. They can be assigned after the students have
developed some expertise in the subject matter.

Additional Photos.

The relevance of knowing the subject matter is reflected
by realistic 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.

New Problems.

There are approximately 50%, or about 850, new problems
added to this edition including aerospace and petroleum engineering, and
biomechanics applications. Also, this new edition now has approximately 17% more
problems than in the previous edition.
