The cross section of a steel beam is shown in the figure. This beam is subjected to a bending moment M having its vector at an angle θ to the z axis.
Determine the orientation of the neutral axis and calculate the maximum tensile stress σt and maximum compressive stress σc in the beam. Assume that θ = 22.5° and M = 4.5 kN m. Use cross sectional properties Ix1 = 93.14 x 106 mm4, Iy1 = 152.7 x 106 mm4, and θp = 27.3°.
