Ignore the weight of the beam.Load:PD = 520 lbPLr = 2,400 lbLoad combination:D + LrSpan:L = 8 ftMember size:4 x 14Stress grade and species:No. 1 Douglas Fir-LarchUnbraced length:lu = 0Moisture content:MC > 19 percentLive load deflection limit:Allow. Δ ≤ L/360

The chаnces оf finding а sоng spаrrоw (Melospiza melodia) on Madarte Island, Canada, with beak that is greater than 10 percent different in size from the population mean beak size is 4 in 10,000. The chances of finding a cactus finch (Geospiza scandens) on Daphne Major with a beak that is greater than 10% different in size from the population mean beak size is 4 in 100. This suggests that natural selection is unlikely to occur in the sparrows.
