Theory of Machines
Definition
Theory of Machines is a branch of science dealing with the study of relative motion between the various parts of a machine and forces which act on them. Theory of Machines has two sub branches namely Kinematics and Dynamics.
Kinematics deals with the study of relative motion between the various parts of a machine. The force which act on them would be static in nature.
Dynamics deals with the study of relative motion between the various parts of a machine. The force which act on them would be static or dynamic in nature. Dynamics has two sub branches namely Kinetics and Statics.
Kinetics is a branch of theory of machine which deals with various forces when the body is moving whereas Statics is a branch of theory of machine which deals with various forces when the body is stationary.
Mechanism
Mechanism is a combination of rigid or restraining bodies which are so shaped and connected that they move upon each other with definite relative motionA machine may be defined as an assemblage[1] of resistant bodies whose relative motions are successfully constrained so that some form of natural energy may be modified or transmitted to do some special kind of work.
