About the Author
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.
