Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_16

5/16 Develop general expressions for the instantaneous velocity and acceleration of point \(A\) of the square plate, which rotates about a fixed axis through point \(O\). Take all variables to be positive. Then evaluate your expressions for \(\theta = 30^\circ\), \(b = 8\text{ in.}\), \(\omega = 1.4\text{ rad/sec}\), and \(\alpha = 2.5\text{ rad/sec}^2\).
