WHAT IS A MACHINE ?

MACHINE - An apparatus using mechanical power and having several parts, each with definite function and together performing a particular task.

•  The word machine derives from latin word machina .
•  Machines are assembled from standardized types of components. These elements consist of  mechanisms that control movement in various ways such as gear  trains,transistor switches, belt  or chain drives, linkages, cam and   follower  systems, brakes and clutches, and structural components such as frame  members and fasteners.
•  Modern machines include sensors, actuators and computer controllers. The shape, texture   and color of covers provide a styling and operational interface between the mechanical components of a machine and its users.
