Answer 1

Please clarify ur questions dear friends

Answer 2

In engineering, a mechanism is a device that transforms input forces and movement into a desired set of output forces and movement. Mechanisms generally consist of moving components that can include:

Gears and gear trainsBelt and chain drivesCam and followersLinkageFriction devices, such as brakes and clutchesStructural components such as a frame, fasteners, bearings, springs, lubricantsVarious machine elements, such as splines, pins, and keys[1]

The German scientist Reuleaux[2] provides the definition "a machine is a combination of resistant bodies so arranged that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinate motion."[3] In this context, his use of machine is generally interpreted to mean mechanism.

The combination of force and movement defines power, and a mechanism manages power to achieve a desired set of forces and movement.

A mechanism is usually a piece of a larger process or mechanical system. Sometimes an entire machine may be referred to as a mechanism. Examples are the steering mechanism in a car, or the winding mechanism of a wristwatch. Multiple mechanisms are machines.
