Question

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 on)

a. ( ω1 - ω2)2r

b. ( ω1 - ω2)r selected: at this answer is incorrect.

d. ω1.ω2.r

Answer 1

The correct answer will be ( ω1 + ω2)r
