Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_112

5/112 The system of Prob. 5/81 is repeated here. Crank \(OA\) rotates with a constant counterclockwise angular velocity of \(9 \text{ rad/s}\). Determine the angular acceleration \(\alpha_{AB}\) of link \(AB\) for the position shown. (From Prob. 5/81: \(OA = 80 \text{ mm}\), \(AB = 200 \text{ mm}\), and the horizontal slot for roller \(B\) is located \(100 \text{ mm}\) vertically above the fixed pivot \(O\). In the position shown, crank \(OA\) is vertical.)
