PROBLEM 4.71 A bar of rectangular cross section shown is made of a steel that is assumed to be elastoplastic with E = 200 GPa and Oy = 320 MPa. Determine the bending moment M for which (a) yield first occurs, (b) the plastic zones at the top and bottom of the bar are 12 mm thick. Draw the stress diagrams side-by-side with the cross section for each case (a and b) and write the relevant values of stresses on the diagram. 30 mm 50 mm
