Summary:

This thorough and comprehensive web-enhanced edition has been updated and enhanced -- No other book has a web connection like this one! The software associated with the book makes it very useful for designing and analyzing linkage and CAM mechanisms. Web-enhanced features include free access to ADAMS™ software, " over 200 animated movie files of mechanisms and machines, and a new CAM design package. New material includes coverage of type synthesis, robot grippers, and curvature cognates, while retaining coverage of traditional material with a significant treatment of kinematic synthesis. All material is explored both graphically and analytically -- Graphical methods are used to fully explain basic principles. Features in-depth and rigorous discussions on displacement and velocity analysis; acceleration and force analysis; and cam design. For professionals interested in Kinematics, Mechanisms, and Dynamics.
