5.27 The airplane's weight is W = 2400 lb. Its brakes keep the rear wheels locked. The front (nose) wheel can turn freely, and so the ground exerts no horizontal force on it. The force T exerted by the airplane's propeller is horizontal. (a) Draw the free-body diagram of the airplane. Determine the reaction exerted on the nose wheel and the total normal reaction exerted on the rear wheels (b) when T = 0; (c) when T = 250 lb. T 4 ft W A-s ft B 2 ft' Problem 5.27
