5. For the following pin-collected link assembly, link AO is pinned at point O, and moves with angular velocity W and angular acceleration a (both counterclockwise). 4) if W = 4.0 rad/s and a = 6.3 rad/s2, length I = 1.5 m, and angle 0= 36°, what is the magnitude of the angular velocity of link AB? Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. 0.5 m 0, a B Your Answer: Answer units

2. Two rigid links are rotating in the horizontal plane as shown in the figure below. The left-most link rotates with angular rate ₁ of 4 rad/s. The end of the right-most link holds a pin which is confined to move along a slot in the other link. The length of the right-most link 72 is 0.45 m. Determine the angular rate ₂ of the second link at the instant shown. Use 0₁ = 30°, 0₂ = 60°, and r₁ = 0.6 m. 0
