CLARKSON UNIVERSITY Department of Mechanical and Aeronautical Engineering AE/ME 350 Aircraft Structural Analysis (Fall 2010) Test #1 Sept 30, 2010 Closed book Closed notes Time : 1:15 hour 1. Imagine that you are responsible for structural design of a supersonic transport airplane. What are the five most important structural design requirements (criteria) that you must satisfy? (5) 2. Aircraft wing comprises different types of structural elements designed to carry specific loads. Give one example for each of these structural elements: axial member, shear panel, bending member, and torsion element. (5) 3. Consider a constant shear flow q on a closed thin-walled section of arbitrary shape as shown in Fig. 1. Show that the resultant torque 2 TA q , where A = Area enclosed by the shear flow. (5) q x y Fig. 1 4. Consider a rectangular plate with a direct tensile stress of 100 N/mm 2 and a shear stress of 50 N/mm 2 . Calculate (i) the principal stresses, (ii) orientation of principal planes (wrt vertical axis), and (iii) if a hole is to be drilled such that there is no shear stress along the hole, what should be the orientation of the hole.
