## Sample Me6401 important questions :

1. What is Kinematics?

Kinematics is the study of motion (position, velocity, acceleration). A major goal of
Understanding kinematics is to develop the ability to design a system that will satisfy Specified motion requirements. This will be the emphasis of this class.

2. What is Kinetics?

Kinetics is the study of effect of forces on moving bodies. Good kinematic design
should produce good kinetics.

A link is defined as a member or a combination of members of a mechanism
connecting other members and having relative motion between them. The link may consist of one or more resistant bodies. A link may be called as kinematic link or element. Eg: Reciprocating steam engine.

4. Define Kinematic Pair.

Kinematic pair is a joint of two links having relative motion between them. The types of kinematic pair are classified according to
Nature of contact (lower pair, higher pair)
To nature of mechanical contact (Closed pair, unclosed pair)
Nature of relative motion (Sliding pair, turning pair, rolling pair, screw pair,
spherical pair)

5. Define Kinematic Chain

When the kinematic pairs are coupled in such a way that the last link is joined to the first link to transmit definite motion it is called a kinematic chain.
Eg: The crank shaft of an engine forms a kinematic pair with the bearings which are fixed in a pair, the connecting rod with the crank forms a second kinematic pair, the piston with the connecting rod forms a third pair and the piston with the cylinder forms the fourth pair. The total combination of these links is a kinematic chain.

Eg: Lawn mower.
