A flanged wooden shape is used to support the loads shown on the beam. The dimensions of the shape are shown in the second figure. Assume LAB = 7 ft, LBC= 3 ft, LCD= 3 ft, LDE = 4 ft, Pc= 1830 lb, PE = 1730 lb, WAB=940 lb/ft, b = 7 in., b₂= 2 in., b3= 5 ín., d₁= 2 in., d₂ = 9 in., dz= 2 in. Consider the entire 17-ft length of the beam and determine: (a) the maximum tension bending stress of at any location along the beam, and (b) the maximum compression bending stress og at any location along the beam. Answers: (a) OT (b) oc = = i i WAB LAB B Pc LBC b₁ b3 D LCD LDE C -b₂ d₁ psi. psi. d₂ d3 PE
