Question

The cross-sectional dimensions of the beam shown in the figure are a = 4.2 in., b = 4.7 in., d = 4.2 in., and t = 0.31 in. The internal bending moment about the z centroidal axis is Mz = -3.60 kip-ft. Determine (a) the maximum tension bending stress (a positive number) in the beam. (b) the maximum compression bending stress (a negative number) in the beam. Answers: (a) σmax T = psi (b) σmax C = psi
