Problem 8.11. Thin-walled C-channel with variable thickness A beam of length \( L \) with the thin-walled, C-channel cross-section shown in fig. \( 8.21 \) is simply supported at both ends and carries a transverse distributed loading, \( p_{0} \), acting along axis \( \bar{\imath}_{2} \) at point C. (1) Determine the location of the centroid. (2) Find the centroidal bending stiffnesses. (3) Find the location and magnitude of the maximum axial stress. (4) Sketch the distribution of axial stress over the cross-section for the section where the maximum bending moment occurs.
