Consider the two beam cross-sections shown in the figure below. Cross-section 1 has b = 0.5 m and hi = 1.0 m. Cross-section 2 has b = 12.02 m, h = 1.0 m, and tweb = 0.02 m. Both cross-sections have the same area. b b2 y h tflange h tweb tflange Cross-section 1 Cross-section 2 a) Calculate flange for cross-section 2 and Ix for each cross-section. [5 points] b) If the maximum bending stress that can be applied to each cross-section is 450 MPa, calculate the maximum bending moment that can be applied to each cross-section. [5 points]
