The most highly developed part of the science is called the theory of machines or mechanisms. It deals primarily with characteristics that are common to all mechanisms, regardless of the specific purpose of the machine, instrument or device. For example, the same mechanism in the form of gears for converting rotary motion may be used in motor vehicles, clocks or mixing equipments for the chemical industry. In all of these cases the same conversion of motion is required; therefore the methods of studying and designing such mechanisms have a great deal in common and belong to the theory of machine. The other part of the science deals with the methods of research and development that are common to machines in various areas of technology. The two parts of the science are inseparably interrelated, since mechanisms are the basis of virtually all machines.


The subject Theory of Machines may be defined as that branch of Engineering – Science, which deals with the study of relative motion between the various parts of machine, and forces which act on them. The knowledge of this subject is very essential for an engineer in designing the various parts of a machine.

A machine consists of an actuator input, a system of mechanisms that generate the output forces and movement, and an interface to the user. Electric motors, hydraulic and pneumatic actuators provide the input forces and movement. This input is shaped by mechanisms consisting of gears and gear trains, belt and chain drives, cam and follower mechanisms, and linkages as well as friction devices such as brakes and clutches. Structural components consist of the frame, fasteners, bearings, springs, lubricants and seals, as well as a variety of specialized machine elements such as splines, pins and keys. The user interface ranges from switches and buttons to programmable logic controllers and includes the covers that provide texture, color and styling.
