Prob. 1 A thin-walled beam has the cross-section shown in the figure below. If the beam is subjected to a bending moment Mx in the plane of the vertical web: Web Yref 2t 3.4 y= 6.7 xc 2h Bottom Flange t h = 10 units length t = 0.1 units length x and y in units length 2h 25 X ref 1. Find the section properties lxx, lyy and Ixy 2. Find the direct stress distribution equation in the beam cross-section (15 pts) (10 pts) Pay attention: x, and y are all given. There is no need to calculate them! Prob. 1 A thin-walled beam has the cross-section shown in the figure below.
