A constant torque M exceeds the moment about O due to the force F on the plunger, and an angular acceleration θ¨ = 100(1 − cos θ) rad/s² results. If the crank OA is released from rest at B, where θ = 30°, and strikes the stop at C, where θ = 150°, plot the angular velocity θ˙ as a function of θ and fi nd the time t for the crank to rotate from θ = 90° to θ = 150°.
