Question:

Solve Prob. 15.172 when ? = 90?. Problem 15.172: Rod AD is bent in the shape of an arc of a circle of radius b = 150 mm. The position of the rod is controlled by pin B which slides in a horizontal slot and also slides along the rod. Knowing that at the instant shown pin B moves to the right at a constant speed of 75 mm/s, determine(a) The angular velocity of the rod,(b) The angular acceleration of the rod.
