A column with a wide-flange section has a flange width b = 400 mm, height h = 400 mm, web thickness tw = 13 mm, and flange thickness tf = 21 mm (Figure 1). Calculate the stresses at a point 75 mm above the neutral axis if the section supports a tensile normal force N = 2.4 kN at the centroid, shear force V = 6 kN, and bending moment M = 4 kN⋅m as shown (Figure 2).

a) Calculate the normal stress at the point due to the internal normal force on the section.

b) Calculate the magnitude of the shear stress at the point due to the internal shear on the section.

c) Calculate the combined normal stress at the point due to internal normal force and the internal bending moment on the section.
