QUESTION 4b The system shown in Figure Q4b consists of rollers A and B, and rod AB of mass 3 kg. The system is attached to a spring with stiffness k 100 N/m. If the roller rolls without slipping, determine the velocity of roller B at the instant when 30°. The system is released from rest when ?-0° at which the spring is compressed by 0.5 m. A constant horizontal force P 10 N acts at point C. Figure Q4b...
