CLARKSON UNIVERSITY Department of Mechanical and Aeronautical Engineering AE/ME 350 Aircraft Structural Analysis (Fall 2010) Sample Test #2 Closed book Closed notes Time 1:15 hour 1. Sketch a V-n diagram and label the axes and the limit lines. (5) 2. What is the significance of the shear center of a beam cross-section? (5) 3. Determine the shear flow distribution in walls AB, BC and CD for the thin-walled beam of uniform cross-section (outer dimension 80 mm x 80 mm) as shown below. A shear force of 2000 N is acting vertically up through the shear center. The ‘cut’ at point A is infinitesimally small. Use I y= 85.35 cm 4 . (25) 40 40 80 2.5 All dimensions in mm A B C D 4. Determine the shear flow and shear force in each cell of the multi-cell thin-walled box beam subjected to external shear force and torque simultaneously. Check your answers by satisfying balance of forces.
