5. For the following pin-collected link assembly, link AO is pinned at point O, and moves with angular velocity and angular acceleration a (both counterclockwise). 2) if W = 3.7 rad/s and a = 7.6 rad/s², what is the magnitude of the linear velocity of point A? Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. B Your Answer: 0 Answer A 0.5 m units ω, α

Bar AB is rotating about A with an angular velocity of wAB 2 rad/s counterclockwise. At this instant bar BC is horizontal. Find the Wac and also, velocity of collar C. Note. You must solve the problem in the way that we solved in the class. Use Vg VA+ wX TB/A and express the vectors in Cartesian vector form. Other solutions will not be evaluated. Solve the problem step by step, and clearly show your work. 25 35 mm 170 mm
