engineering recuitment JSSC JE Mock Test 2023 Theory of Machines Velocity and Acceleration Analysis Velocity of Rubbing
Two links OA and OB are connected by a pin joint at 0. The angular velocities of OA and OB are ωa and ωb in the clock wise and counter - clock wise respectively. If the radius of pin at O is r, the rubbing velocity is
1
(ωa + ωb)r
2
(ωa - ωb)r
3
(ωa + ωb)2r
4
(ωa - ωb)2r
