QUESTION 2 Figure Q2 shows a punching mechanism. Both the disc radius, r and the length of rod AB, L are 0.3 meter. At the instant shown, the end of the plunger, ac accelerates at a rate of 10 m/s. Meanwhile, disc OA is rotating with angular velocity, WOA = 8 rad/s about point O and angular velocity of member AB, WAB at 10 rad/s (U). Determine: i. Angular acceleration of disc OA, OA ii. Angular acceleration of member AB, AB SOLUTIONS Lon = 267.55 rad/s LAB = 284.44 rod/82 B Figure Q2 ac
