A simply-supported beam of rectangular cross-section (width w and height h) is subjected to the loads as shown in the figure (i). The enlarged view of the beam cross-section is shown in figure (ii). The coordinate system is indicated in the figures. Assuming Euler-Bernoulli beam approximation, the shear stress ππ₯π§ and normal stress ππ₯π₯ at the origin, O are respectively given by
