A simply supported beam, 12 in long, is to support a load of 488 lbf acting 3 in from the left support, as shown in Figure. The beam is an I beam with the cross-sectional dimensions shown. To simplify the calculations, assume a cross section with square corners, as shown in Figure. Points of interest are labeled (a, b, c, and d) at distances y from the neutral axis of 0 in, 1.240 in, 1.240 in, and 1.5 in. At the critical axial location along the beam, find the following information. (1) Determine the profile of the distribution of the transverse shear stress, obtaining values at each of the points of interest (a, b, c, and d). (2) Determine the bending stresses at the points of interest (a, b, c, and d). (3) Determine the maximum shear stresses at the points of interest and compare them. 0 -3 in- R₁ -366 16 488 lbf lbf -9 in R₂=122 lbl 3.000 in Figure 8 0.260 in E 4-2.33 in- -0.170 in [0.260 in 1.24 in 1.08 in d b A simply supported beam, 12 in long, is to support a load of 488 lbf acting 3 in from the left support, as shown in Figure.
