The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ?1 rad/s in the clockwise direction and the link OB turns with angular velocity ?2 rad/s in the clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O)
Options
A. ?1.?2.r
B. ( ?1 - ?2)r
C. ( ?1 + ?2)r
D. ( ?1 - ?2)2r
Correct Answer
( ?1 - ?2)r
