Figure Q.88 shown a mechanism ABCD used for making medicinal power. A punch with tip point O is rigidly attached to the link CD. At the instant considered, the crank AB is rotating at a speed of 1 rad/s under the action of a torque (T) of 20 N-m to overcome the resistance force (F) of 10 N acting at O which is perpendicular to the line OD, is 1 m the angular velocity of the link CD is
