Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_165

*5/165 All conditions of Prob. 5/163 remain the same, except the counterclockwise angular velocity of crank $OA$ is $10 \text{ rad/s}$ when $\theta = 0$ and the constant counterclockwise angular acceleration of the crank is $20 \text{ rad/s}^2$. Determine and plot as functions of the crank angle $\theta$ the angular velocities of bars $AB$ and $BC$ over the range $0 \le \theta \le 360^\circ$. State the maximum absolute value of each angular velocity and the value of $\theta$ at which it occurs. (Conditions from Prob 5/163: $r_{OA} = 80 \text{ mm}$, $L_{AB} = 240 \text{ mm}$, $L_{BC} = 200 \text{ mm}$. The fixed pivot $O$ is at the origin, and fixed pivot $C$ is located $190 \text{ mm}$ to the left and $70 \text{ mm}$ below $O$.)
