Theory of Machines is designed mainly for the students of mechanical engineering. It focuses on recent developments on the new mechanisms in the field of kinematics. The text seamlessly combines its 40 year experience with the latest methods to be used by students to understand definitions and problems that are solved using elementary methods. The book covers the entire syllabus with a holistic approach. Contents such as the Kinematics of Motion, Kinetics of Motion, Simple Harmonic Motion, Simple Mechanisms, Velocity in Mechanisms, Turning Moment Diagrams and Flywheel, Steam Engine Valves and Reversing Gears, Torsional Vibrations, Computer Aided Analysis and Synthesis of Mechanisms and Automatic Control formed an important part and have been explained very well.
