The mean dimensions of Ihe cross section of the leading edge and torsion box of an airplane wing can be approximated as shown. If the wing is subjected to a torque of 4.5 MN • m and the wall thickness is 10 mm. determine the average shear stress developed in the wmg and the angle of twist per meter length of the wing. The wing is made of 2014-T6 aluminum alloy.
