(6) For the composite beam shown in the figure, which is bended about a horizontal axis by a couple of moment M = 1000 N · m, determine the maximum stresses in Materials A and B. Material A, E = 210 GPa 20 mm M 40 mm Material B, E = 69 GPa 20 mm

The beam shown in the figure consists of a W360 x 79 structural steel wide-flange shape [E = 200 GPa; I = 225 × 106 mm¹]. For the loading shown, determine: (a) the reactions at A, B, and C. Enter a positive value for a reaction force that acts upward on the beam, or a negative value for a reaction force that acts downward. (b) the magnitude of the maximum bending stress in the beam. Enter a positive value for the magnitude. Note: Use the tabulated value for the section modulus S from Appendix B directly in the stress calculation. Although S is related to the area moment of inertia I and the cross-section depth d, due to round-off in the tabulated data for S, I, and d, a slightly different answer for the bending stress is obtained using S directly as compared to the result obtained in using I and d. Of course, performing the calculation using either S directly, or using I and d, the answer will likely be within the required tolerance. Assume L₁ = 3.2 m, L₂ = 5.3 m, M = 200 kN-m, and w =…
