Question

Review The collar C is pinned to rod CD while it slides on rod AB. Rod AB has an angular velocity of WAB = 3 rad/s and an angular acceleration of QAB = 9 rad/s, both acting counterclockwise. Suppose that a = 4 m and b = 3 m. (Figure 1) Part A Determine the angular velocity of rod CD at the instant shown measured counterclockwise. Express your answer using three significant figures. Enter positive value if the angular velocity is counterclockwise and negative value if the angular velocity is clockwise. IVO AQ 1 vec ?

At the given instant the slider velocity (it is at rest) rod AB is zero. so there is no coriolis acceleration. on its fositio But the slider changes is it hay the sliding velocity and comes due to rod this sliding relocity acting along (ie, 6wa acceleration AB net 2 a) AR so, the tangential acceleration remains in both cases same a LAB bo AD a XAB btco 4 x 9 = 3x Les ㅕ 12. rad Clockwise 기 2 12 rad Counter clockwiese.
