The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω1 rad/s in the clockwise direction and the link OB turns with angular velocity ω2 rad/s in the clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O)

(w1-w2)r - if links moves in same direction.
(w1+w2)r - if links moves in opposite direction.
(w1+w2)r - if links moves in opposite direction.

When the two bodies moves in same direction then relative velocity is (w1-w2)r.
