Theory of Machines and Mechanisms provides a text for the complete study of displacements, velocities, accelerations, and static and dynamic forces required for the proper design of mechanical linkages, cams, and geared systems. The authors present the background, notation, and nomenclature essential for students to understand the various independent technical approaches that exist in the field of mechanisms, kinematics, and dynamics.

Now fully revised in its fourth edition, this text is ideal for senior undergraduate or graduate students in mechanical engineering who are taking a course in kinematics and/or machine dynamics.

New to the Fourth Edition

- Includes more worked examples throughout, and many new and updated end-of-chapter homework problems

- Coverage of helical gears, bevel gears, worms, and worm gears is now integrated into a single chapter

- Material on planar and spatial dynamic force analysis is now integrated into a single chapter

- A completely new chapter has been added on multi-degree-of-freedom planar linkage analysis

- The chapter on kinematic synthesis has been markedly expanded, and now includes three and four accuracy position graphical methods

- The chapter on static force analysis has been expanded to included coverage of buckling of axially-loaded two-force members under compression

Supplements

- In-text CD includes Working Model animations of many figures from the text to help students visualize and comprehend their movement

- A companion website for instructors (www.oup.com/us/uicker) provides additional information and resources, including PowerPoint-based slides of figures from the text

John J. Uicker, Jr. is a Professor of Mechanical Engineering at the University of Wisconsin - Madison. His teaching and research specialties are in solid geometric modeling, modeling of mechanical motion and their application to computer-aided design and manufacture. He received his Ph.D. in mechanical engineering from Northwestern University and joined the University of Wisconsin faculty in 1967. Uicker is one of the founding members of the US Council for the Theory of Machines and Mechanisms. He served for several years as editor-in-chief of the Mechanism and MachineTheory.

Gordon R. Pennock is an Associate Professor of Mechanical Engineering at Purdue University, West Lafayette, Indiana. His teaching experience is primarily in the area of machine design. His research specialties are in theoretical kinematics and in the dynamics of mechanical motion. He has applied his research to robotics, rotary machinery and biomechanics, including kinematics and dynamics of articulated rigid-body mechanical systems.
He received his Ph.D. degree in mechanical engineering from the University of California, Davis. Since joining the Purdue University faculty in 1983, he has served on several national committees and international program committees. He is the Student Section Advisor of the American Society of Mechanical Engineers (ASME) at Purdue University, Region VI College Relations Chairman, Senior Representative on the Student Section Committee, and a member of the Board on Student Affairs. He is also an Associate of the Internal Combustion Engine Division, ASME, and served as the Technical Committee Chairman of Mechanical Design, Internal Combustion Engine Division, from 1993-1997. He is a Fellow of the American Society of Mechanical Engineers.
Joseph E. Shigley (deceased May 1994) was Professor Emeritus of Mechanical Engineering at the University of Michigan and a Fellow in the American Society of Mechanical Engineers. He held the Mechanisms Committee Award, the Worcester Reed Warner medal and the Machine Design Award. He was an author of eight books, including Mechanical Engineering Design (with Charles R. Mischke) and Applied Mechanics of Materials. He was also Coeditor-in-Chief of the Standard Handbook of Machine Design. He first wrote Kinematic Analysis of Mechanisms in 1958 and Dynamic Analysis of Machines in 1961. These texts became published in a single volume titled Theory of Machines in 1961 and evolved over the years to the current text, Theory of Machines and Mechanisms, now in its third edition.
Professor Shigley was awarded the B.S.M.E. and B.S.E.E. degrees at Purdue University and the M.S. at the University of Michigan. After several years in industry, he devoted his career to teaching, writing, and service to his profession starting first at Clemson University and later at the University of Michigan. His textbooks have been widely used throughout the United States and abroad.
