Kinematics is the branch of science which deals with motion without considering the forces which causes the motion. On the other hand, kinetics is the branch of science which also takes forces which causes motion as well as weight and inertia effects in study.

Kinematic Link and Kinematic Pair

Link: It is defined as a machine element having relative motion with respect to other parts of machine element.

Kinematic pair is defined as a joint of two links which permits relative motion between elements or links. Kinematic pair is constituted when there is mechanical contact between them and having arrangement of mechanism.

Lower pair is said to be constituted when two elements have surface contact between them.

Higher pair is said to be constituted when two element have point contact between them.


Kinematic Chain

Kinematic chain is one in which number of links are so connected that relative motion of any point on a page link with respect to any other point on the other page link follows a governing law
L = 2/3(J+2) Where, L = Number of links, J = Number of Joints

or
J = 3/2(L)-2, Where, H = Number of Higher pairs

One Higher pair = Two lower pair


The criterion for a chain to be constrained:


J+H/2 = 3/2(L)-2,

Where, H = Number of Higher pairs and J =Number of binary joints in chain
If R.H.S. = L.H.S. , Chain is said to be locked.

Mechanism

If the one of the page link of constrained kinematic chain is fixed, it results into 'Mechanism'

A mechanism with four links is called simple mechanism. Mechanism with single degree of freedom are having only even number of links.

Real life example is automobile propelling system which contains links in form of piston, connecting rod and cranks shaft to which flywheel and rear tire is attached.
