2. The following wing has the shown idealized cross-section at its root, and is made of 7075- T6 Aluminum. The root cross-section has A = 1.355e-6 m² and 6.42e-4 m². I, I? = 5.4288e-6 m. Note the dimension units in both figures. (a) Calculate po for zero strength M.S. (b) Calculate the longitudinal stress distribution at the critical cross-section (c) Sketch the above stress on the cross-section (d) Calculate the wing bending displacement distribution (e) Calculate the maximum bending displacement -0.05 PL- 3m (12) (11) @O (10) ZA 0.04 P, L² 0.2 PoL + (3) 4 × 60 2 m €0 (8) A 001 6 y
