Question:
A cold-formed steel section is made by folding a steel plate to form a structural section such as that shown in the figure. This beam is subjected to bending moment M = 2 kip-in. at angle θ = 108 to the z-axis. Find the centroid and the orientation of the neutral axis. Find flexural normal stresses at points A and B (see figure). Use the flexure formula based on principal axes and then confirm your solution using the general flexure formula.
