to increase their analytical and design capabilities. Computer-aided design problems are
provided in particular to encourage students to use computers in design. A solutions
manual is available that contains answers to some of the problems.
Such organization emphasizes the importance of safety in machine element design,
helps students who may have had little exposure to machines, structures or industrial
practice to build a clear structure of the course and to link analysis with design.
Design requires extensive use of knowledge in mechanical engineering science, such
as mechanical drawing, materials properties, statics and dynamics, mechanics of materi-
als, synthesis and analysis of mechanisms and machines, manufacturing processes, geo-
metric dimensioning and tolerancing, fluid mechanics, computer-aided design and so
on. Fundamentals necessary for the entire book are introduced in Part I, others required
for specific machine elements are embedded in relevant chapters. For example, tribol-
ogy and fluid mechanics are introduced in the chapter on sliding bearings. Such an
arrangement helps students effectively bridge the gap between basic scientific knowl-
edge and design activity, assist their better understanding of complex working mech-
anism of machine elements and ultimately promote their engineering and innovation
capability in mechanical design.
This book provides general methodology and fundamentals for the analysis and design
of common machine elements, with an aim to help students gain competence in apply-
ing these methods and procedures to machine element design. When designing machine
elements for important applications, designers should check all important data from
standards, design handbooks or industrial manuals. The book uses the International Sys-
tem of Units, with conversion to other unit systems introduced. The book evolved from
lecture notes initially prepared for international undergraduates in a mechanical design
course, with a hope to increase the competency of mechanical engineering graduates to
function well in a globalized profession and to help them communicate effectively and
cooperate productively in international collaborative design activities.
Although the author has made every effort to ensure accuracy and conformity with
good engineering practice, errors are unavoidable and constructive suggestions and
feedback are warmly welcomed.
Finally, I would like to express my appreciation to Dr K. Yahiaoui from University of
Wolverhampton for reviewing Chapter 6 and all other reviewers who have contributed
to this text. Their reviews greatly enhanced the quality of the book. I am especially
grateful to my graduate students for their patiently preparing all the illustrations, to
my colleagues for the helpful discussions and to my undergraduate students for their
feedback about the book.
Thanks are also due to editorial staff and many other individuals in John Wiley & Sons
who have contributed their talents and energy to producing this book.
Special thanks are due to my family for their understanding, support and encourage-
ment during more than 10 years’ preparation for the book.
