At a given instant, rod AB has the angular motions shown in the previous figure. Determine the angular acceleration of rod CD at this instant if the relative velocity of C with respect to A is 18ft/s and ω CD=9 rad/s.

A disk oscillates about its axis of rotation given by its angular acceleration of ∝ = -kθ. First determine the value of k for which,  w= 16 rad/s when θ = 0 and θ = 6 radians when w= 0. Then determine the angular velocity when θ = 1.2 radians.

At the instant shown in (Figure 1). rod AB has an angular velocity w AB = 2.4 rad/s and an angular acceleration AB= 10 rad/s². The collar at C is pin-connected to CD and slides over AB.
