Calculate the stress distribution induced by a bending moment and axial force of 120 kNm and 90 kN, respectively. Assume the section to be I-shaped and doubly-symmetric with A = 10,500 mm2, I = 372 × 106 mm4 and E = 200,000 MPa. Adopt a centroidal coordinate system with origin at mid-height of the section (of depth 460 mm).
