Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_81

5/81 Crank OA rotates with a counterclockwise angular velocity of 9 rad/s. By the method of this article, determine the angular velocity \(\omega\) of link AB and the velocity of roller B for the position illustrated. Also, find the velocity of the center G of link AB. Known Quantities from Diagram: Length of crank \(OA\), \(r_{OA} = 80 \text{ mm}\). Length of link \(AB\), \(L_{AB} = 200 \text{ mm}\). Angular velocity of \(OA\), \(\omega_{OA} = 9 \text{ rad/s}\) (Counterclockwise). Vertical distance from pivot \(O\) to the horizontal slot, \(h = 100 \text{ mm}\). In the "position illustrated", crank \(OA\) is horizontal.
