A wооd member is lоаded аs shown. Using ASD, determine the mаximum axial 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 = 5,000 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 8,000 lbPE = 5,500 lbQD = 3,500 lbQL = 3,000 lbQLr = 3,000 lbQS = 2,500 lbQR = 1,000 lbQW = 0 lbQE = 0 lbSpan:L = 13 ft Member size:4 x 14 Stress grade and species:No. 2 Douglas Fir-Larch Unbraced length:lu = L/2 = 6.5 ft Moisture content:MC < 19 percent
