Question

Consider a constant cross section aircraft wing that is 38 feet long on each side of the aircraft. In flight, the wing carries the full load of the plane, 52,000 pounds. Assume this load is equally shared between the wing on the left and right side of the aircraft and is evenly distributed along the wing as a uniform load. If the aluminum wing has an I of 745 in^4 and aluminum has an E of 10.1 *10^6 psi, how much would the end of the wing deflect relative to the fuselage of the aircraft compared to the position it has when aircraft is on the ground.
