Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_164

*5/164 If all conditions in the previous problem remain the same, determine and plot as functions of the crank angle \(\theta\) the angular accelerations of bars \(AB\) and \(BC\) over the range \(0 \le \theta \le 360^\circ\). State the maximum absolute value of each angular acceleration and the value of \(\theta\) at which it occurs. (Conditions from Problem 5/163: The crank \(OA\) of the four-bar linkage is driven at a constant counterclockwise angular velocity \(\omega_0 = 10 \text{ rad/s}\). Dimensions: \(OA = 80 \text{ mm}\), \(AB = 240 \text{ mm}\), \(BC = 200 \text{ mm}\). The horizontal distance from \(O\) to \(C\) is \(190 \text{ mm}\), and the vertical distance from the horizontal through \(O\) down to \(C\) is \(70 \text{ mm}\).)
