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 in., d=2 in., d2= 9 in., d3= 2 in. Consider the entire 17-ft length of the beam and determine: (a) the maximum tension bending stress or at any location along the beam, and (b) the maximum compression bending stress oc at any location along the beam. PE Answers: (a) or = (b) %. = WAB LAB B Pc ↓ LBC b₁ b3 C LCD -b₂ psi. D d₁ psi. dy LDE d₂ E
