Extracted text: PROBLEM 4. An airplane wing made of 2014-T6 aluminum alloy is modeled as a closed cross-section thin walled tube as shown in the figure. A uniformly distributed torque of 500 kN.m/m is applied along the leading edge of the wing. Determine, (a) The maximum shear stress that will occur on the wing (b) The angle of twist of the wing tip. 8000 mm t = 500 kN.m/m mm -12 mm 8 mm 600 mm 400 mm 6 mm 2000 mm
