Mechanical systems are classified into two types:
The motion of the body during translational motion is along a straight line or curved path whereas during rotational motion, the motion of the body is about its own axis.
There are three elements which are dominantly involved in the analysis of translational motion. These are given below:
In the physical model of a mass, it is assumed that its mass is concentrated at the centre of the mass. Figure 5.12 shows that a block of mass M, ABCD is moved and its all particles will undergo an equal displacement.

Therefore, the ...
