In the design of this linkage, motion of the square plate is controlled by the two pivoted links. Link OA has a constant angular velocity ω = 4 rad /s during a short interval of motion. For the instant represented, θ = tan⁻¹ 4 /3 and AB is parallel to the x-axis. For this instant, determine the angular acceleration of both the plate and link CB.
