A thin-walled cantilever with walls of constant thickness t has the cross section shown in Fig. P.15.4. It is loaded by a vertical force W at the tip and a horizontal force 2W at the midsection, both forces acting through the shear center. Determine the distribution of direct stress, according to the basic theory of bending, along the length of the beam for the points 1 and 2 of the cross section.
