A 1-kg collar C slides without friction along the rod OA and is attached to rod BC, by a frictionless pin. The rods rotate in the horizontal plane. At the instant shown BC is rotating counterclockwise and the speed of C is 1 m/s, increasing at a rate of 1.3 m/s. Determine at this instant, (a) the tension in rod BC, (b)the force exerted by the collar on rod OA.
