(1) A thin-walled beam having a uniform wall thickness of 10 mm is subjected to a bending moment M=50 kN-m, as shown in Figure 4(a). Determine the bending stress of point Hand also locate the neutral axis. (2) If a downward shear force P = 100 kN is applied on the beam through the centroid of the cross-section, as shown in Figure 4(b), plot the shear stress distribution on the cross-section. 160 H 10 Z 100 450 100 100 Dimension unit: mm (a)
