The beam has a uniform weight of 5500 pounds. Calculate the average tension in each of the two wires AB and AC if the beam is accelerated to 9 feet per second in 2.5 seconds from rest. If the cables can sustain a maximum tension of 5000 lb. each, determine the possible shortest time to lift the beam with a speed from 2 ft/s to 10ft/s. mass of cables are neglected.
