Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_44

5/44 For the instant represented when \( y = 160 \text{ mm} \), the piston rod of the hydraulic cylinder C imparts a vertical motion to the pin B consisting of \( \dot{y} = 400 \text{ mm/s} \) and \( \ddot{y} = -100 \text{ mm/s}^2 \). For this instant determine the angular velocity \( \omega \) and the angular acceleration \( \alpha \) of link OA. Members OA and AB make equal angles with the horizontal at this instant.
