The airplane in Figure 4.49 has a weight of W = 800, 000 lb and a centroidal mass moment of inertia of IG = 4 × 107 lb·in·sec2 . As the aircraft lands, the rear wheels make contact with the ground and the wing and tail lift forces are Lwing = 0.8W, Ltail = 0.04W. The accelerations of the airplane are ax = −0.2g (to the right) and az = 0.4g (upwards). Find the reactions at the rear wheel, as well as the pitch acceleration of the airplane. Then, determine the forces acting on the support braces of a package weighing 50 lb, located at point B. The pitch angular velocity of the airplane is zero
