3. The V-22 Osprey is a military tilt-rotor aircraft that has vertical takeoff/landing capabilities, yet can also fly in an airplane mode. The maximum loaded weight of the aircraft is 60,000 lbs. The weight of each engine nacelle/proprotor assembly is 4000 lbs. The weight of each wing loaded with fuel is 5000 lbs. Treat each wing as a rectangular box with uniform weight distribution. Your work below should assume the aircraft is hovering (see figure (b)). (a) airplane mode (b) hover mode L=19 ft (a) Determine the vertical load (P) and the effective distributed loading on the wing (wo) using the beam model in bottom figure. (b) Write symbolic expressions for the shear force V (x) and bending moment M(x) in the wing in terms of the given parameters. (c) Provide a rough sketch of V(x) and M(x) and label all significant points. 3.
