KOM 2 Mark Question & Answers


1.       Define Kinematics
Kinematics is the branch of classical mechanics that describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without consideration of the causes of motion.
2.       Define Synthesis and Analysis
Synthesis is the design and facbrication of different parts of mechanism.
Analysis is the study of motions and forces concerning different parts of a mechanism.
3.       Define Mechanism
A mechanism is a device designed to transform input forces and movement into a desired set of output forces and movement. Mechanisms generally consist of moving components such as gears and gear trains, belt and chain drives, cam and follower mechanisms, and linkages as well as friction devices such as brakes and clutches, and structural components such as the frame, fasteners, bearings, springs, lubricants and seals, as well as a variety of specialized machine elements such as splines, pins and keys.
4.       Define a Machine
A machine is a mechanism or a combination of mechanisms which apart from imparting definitive motions to the parts also transmits and modifies the available mechanical energy into some kind of desired work.
5.       What is a rigid body?
Rigid bodies have no distortion,i.e,. the distance between any two points on it remain constant under the action of forces.
6.       What is a resistant body?
These bodies are normally flexible, but on loading becomes rigid.
7.       Define Link.
A resistant body or a group of resistant bodies with rigid connections preventing their relative movement is known as link. Link is a kinematic element.
