The diagram shows the instant when a long slender bar of mass 4.8 kg and length 1.9 m is horizontal. At this instant the mass m= 7.4 kg has a vertical velocity of 3.5 m/s. If the pulley has negligible mass and all friction effects may be ignored, what is the magnitude of the reaction force on the bearing A?
