Link oa is given a clockwise angular velocity
NettetFor a short interval of motion, link OA has a constant angular velocity w = 4.0 rad/s. Determine the angular acceleration aAB (positive if counterclockwise, negative if clockwise) of link AB for the instant when OA is parallel to the horizontal axis through B. 70 mm OA 105 mm 250 mm Answer: aAB = i rad/s2 Question thumb_up 100% NettetDisk D rolls without slipping over the horizontal surface. At the instant shown, point A on bar OA, which is pinned to the fixed point at O at its left end, is moving straight down with constant speed vo. End B of bar AB is pinned to the disk at point B. At this instant, determine, as functions of R and vo, the angular velocities and angular ...
