Question
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 = 8 ft, LBC = 4 ft, LCD = 3 ft, LDE = 5 ft, PC = 1650 lb, PE = 1740 lb, wAB = 680 lb/ft, b1 = 9 in., b2 = 2 in., b3 = 5 in., d1 = 2 in., d2 = 8 in., d3 = 2 in. Consider the entire 20-ft length of the beam and determine: (a) the maximum tension bending stress σT σ T at any location along the beam, and (b) the maximum compression bending stress σC σ C at any location along the beam.
