A beam with mass m1 = 600 kg and length l1 = 4.00 m rests on supports A and B (Fig.), the distance between which is l2 = 1.00 m. A load is suspended from the free end of the beam. The beam presses on support B with a force FB = 7.35 • 103 N. Determine the mass of the load and the force with which the beam presses on support A.
