Problem 2 (20 points) The figure below shows a two-dimensional rigid body that is connected to the ground by two links AB and CD, which are both free to rotate in the plane of the figure so that the angles 0 and ß can change. Length AB = CD= 1.1 m. For the instant represented, the link AB has a clockwise angular velocity of @AB with vB = 10 m/s. Using the instantaneous center of zero velocity method, when 0 = 45° and B = 90°. Find: (a) Instantaneous center of zero velocity of BD (label with IC, be precise, use a straight edge) (b) The magnitude and direction of the angular velocity of rigid body BD (@BD) (c) Magnitude and direction of the velocity of point D. Precisely draw the direction at point D. A 1.2 m 1 k 2.8 m
