Due to an unequal distribution of fuel in the wing tanks, the centers of gravity for the airplane fuselage A and wings B and C are located as shown. Draw a free-body diagram of the airplane. If these components have weights WA = 43000 lb. , WB = 8000 lb., and WC = 6000 lb. determine the normal reactions of the wheels D, E, and F on the ground.
