Prob. 1 A thin-walled beam has the cross-section shown in the figure

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: h/2 Yref Top Flange 2t Web 2t 2.6 y=8.5 2h x Bottom Flange h = 10 units length t = 0.1 units length x and y in units length 2h t Xref 1. Find the section properties lxx and lyy (15 pts) 2. If lxy-192.97 units, find the direct stress distribution equation in the beam cross-section Pay attention: Iyy, x, and are all given. There is no need to calculate them! (10 pts)
