10.4 A beam of the cross section shown is made of a steel which is assumed to be elastoplastic with E 200 GPa and oy 300 MPa. For bendig about the z axis, determine the bending moment and the radius of curvature at which (a) yield first occurs, (b) the plastic zones at the top and bottom of the bar are 20 mm thick. [20.6kN.m, 29.3 m; 26.9 kN.m, 16 m) 20 mm 48 mm 20 mm 14 mm 14 mm 30 mm
