State the relation between relative velocity and motion of link in mechanism.

Relation between Relative Velocity and motion of link in mechanism:
The relative velocity is the velocity of any point with respect to any other some point on the
same link.
Let,
V be the relative velocity of one end w.r.t. other end of link in m/sec
ω be the angular motion in rad/sec &
r as the length of same link in meter
Then, the relation is expressed as;
V = r x ω m/sec
