En -shigley machine design 9th edition

Preface

This text is intended for students beginning the study of mechanical engineering

design. The focus is on blending fundamental development of concepts with practical

specification of components. Students of this text should find that it inherently

directs them into familiarity with both the basis for decisions and the standards of

industrial components. For this reason, as students transition to practicing engineers,

they will find that this text is indispensable as a reference text. The objectives of the

text are to:

• Cover the basics of machine design, including the design process, engineering

mechanics and materials, failure prevention under static and variable loading, and

characteristics of the principal types of mechanical elements

• Offer a practical approach to the subject through a wide range of real-world applications

and examples

• Encourage readers to link design and analysis

• Encourage readers to link fundamental concepts with practical component specification.

New to This Edition

Enhancements and modifications to the ninth edition are described in the following

summaries:

• New and revised end-of-chapter problems. This edition includes 1017 end-ofchapter

problems, a 43 percent increase from the previous edition. Of these problems,

671 are new or revised, providing a fresh slate of problems that do not have

years of previous circulation. Particular attention has been given to adding

problems that provide more practice with the fundamental concepts. With an eye

toward both the instructor and the students, the problems assist in the process of

acquiring knowledge and practice. Multiple problems with variations are available

for the basic concepts, allowing for extra practice and for a rotation of similar

problems between semesters.
