This SI edition of Theory of Machines and Mechanisms, Third Edition, International Version, provides the foundation for the 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 and independent technical approaches that exist in the field of mechanisms, kinematics, and dynamics. Coverage of all analysis and development methods is balanced, with the use of both analytic and graphic tools. In addition, all measurements are presented using the International System of Units (SI). This text is ideal for undergraduate students of mechanical engineering, taking a course on kinematics of machines, dynamics of machines, and/or mechanics of machines.
