Three proposed cross-section configurations for joining three boards are shown in Figure 1. Each board is bx3b (b = <50+sum of last two digits of your roll+last digit of your roll> mm). If the bending moment about the z-axis is 5000 N m, what is the maximum bending stress in each cross-section? Which cross-section is the most effective use of the material in bending? %3D 36
