Mechanical Design of Machine Elements and Machines: AFailure Prevention Perspective   by Jack A. Collins, JohnWiley & Sons, 2003

REVIEWED BY DAVID B. DOONER1

This new textbook targets the Junior-Senior level sequence inmachine design challenging classical machine design texts asso-ciated with authors such as Joseph E. Shigley, Robert C. Juvinall,and Merhyle F. Spotts. The author’s emphasis on failure preven-tion includes the selection of a factor of safety as part of thedesign process. The book is divided into two parts. The first partaddresses  engineering principles  whereas the second part consid-

ers   design applications.The first part diverges from similar machine design texts bytargeting failure prevention as the underlying theme for machinecomponent selection. The many components of failure are intro-duced early in Chapter 2. These concepts include the classicalfailure modes; yielding, ductile and brittle failure, fatigue failure,wear, impact, and buckling along with less traditional failuremodes such as fretting, creep, and corrosion are presented. Spe-cifically, the fracture mechanics approach to predict fatigue failureis introduced and expanded from classical texts on machine ele-ments to provide a more modern assessment of fatigue life.

The second part provides a classical treatment on the design of machine elements such as bearings, springs, fasteners and powerscrews, gear pairs, brakes and clutches by presenting established

design methodologies as set by the appropriate organizations. For

example, the AGMA American Gear Manufacturers Associationmethod of gear rating is demonstrated for both spur and helical

gear pairs. Also presented is an introduction to bevel gear design

and worm and worm wheel gear rating without complicating the

idiosyncrasies of spatial gear kinematics. Included are the less

common elements: pressure vessels, flywheels, as well as non-

direct contact mechanisms consisting of belts, chains, ropes, and

flexible connectors. A concluding chapter gives insight on ma-

chine design versus machine component selection.

The author carefully balances the depth of presentation versus

concept and coverage providing an excellent introduction to the

design of machine elements. Practical example problems are pro-

vided in each chapter to guide the student through the designprocess by illustrating the analysis steps. These problems will be

especially attractive in US based schools as the primary units

system is the inch-pound-second. Sufficient analysis problems are

provided at the end of each chapter for students to master the

material. In Part II, mini open-ended design scenarios are pre-

sented to showcase the non-uniqueness of machine component

specification. Included are problems with illustrative figures as

well as problems without figures such that students can practice

envisioning descriptive scenarios. Further, the concepts are clearly

presented making this book a suitable reference for graduate stu-

dents and engineers interested in a specific topic. It is refreshing to

find failure prevention interwoven into the design of machine el-

ements and I highly recommend this text to colleagues seeking

such perspective.1University of Puerto Rico.
