Mechanism

2.

Kinematic Pair

Answer 1

1.Mechanism

The mechanism is how motion is transmitted and modified in a machine or any arrangement of mechanical elements. The main feature of a machine's mechanism is that all members have restricted motion; that is, the parts may only move in a certain direction relative to one another.

A see-saw is an example of a mechanism; motion is carried equally across a see-saw as long as there is an equal force on both ends. A lever is an example of a mechanism; a lever controls the direction, strength, and quantity of movement. A collection of elements that function or interact in the same way as a machine does.

2.Kinematic Pair

This is made up of two components linked in such a way that one is forced to roll in another fixed element. For example, consider ball and roller bearings. On a level surface, a wheel is rolling.
