Problems Unless directed otherwise, neglect the weight of the beam in the following problems. For standard structural shapes, use the properties tabulated in Appendix B. 2 in 5.1 A beam constructed from 2-in. by 8-in. boards has the cross section shown in the figure. If the maximum bending moment acting in the beam is M = 16000 Ib-ft. determine the maximum bending stress in (a) board 4; and (b) board B. 8 in 5.2 The magnitude of the bending moment acting on the circular cross section of a beam is M - 30000 lb-fR. Calculate the bending stresses at the following points on the cross section: (a) A; (b) B; and (c) D. 2 in -2 in 33.3 mm Flange W 360 x 262 FIG. PS.1 NA 387 mm 21.1 mm Web - 398 mm - FIG. PS.2 FIG. PS.3 5.3 The bending moment acting on the w 360 x 262 section is 460 kN-m. Find the maximum bending stress in (a) the flanges; and (b) the web. See Appendix B-2 for properties of the section.
