A wооd member is lоаded аs shown. Using ASD, determine the mаximum bending stress in the member. Assume normal temperatures, no incising, and that all loads act in the directions shown. Ignore the weight of the member.Load:PD = 4,500 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 5,000 lbPE = 7,500 lbQD = 2,500 lbQL = 0 lbQLr = 1,000 lbQS = 1,000 lbQR = 3,000 lbQW = 0 lbQE = 0 lbSpan:L = 12 ft Member size:4 x 6 Stress grade and species:Select Structural Douglas Fir-Larch Unbraced length:lu = L/2 = 6 ft Moisture content:MC < 19 percent
