The beam shown in the figure consists of a W 360×79 structural steel wide-flange shape [E=200GPa;I=225×106 mm4]. 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​=3.5 m,L2​=5.5 m,M=192kN⋅m and w=98kN/m
