The bar shown in the figure has a square cress section for which the depth and thickness are 40 mm. If an axial force of 800 N is applied along the centroidal axis of the bar's cross- sectional area, determine the average normal stress and average shear stress acting on the material along (a) section plane a-a (b) section plane b-b.
