QUESTIONS Given a simply supported beam that is 20 feet long and is carrying a uniform load of 2.1 klf, which of the following provides less than 1/360 of deflection with the minimum weight of steel? It is made of steel with an Elastic Modulus of 29,000 ksi and a Yield Strength of 50 ksi. W12x22 (lx = 156 in 4, Sx = 25.4 in3, Zx = 29.3 in 3) O W12x65 (lx = 533 in 4, Sx = 87.9 in3, Zx = 96.8 in3) O W16x26 (lx = 301 in 4, Sx = 38.5 in3, Zx = 44.2in3) 0 W18x35 (lx = 510 in 4, Sx = 57.6 in3, Zx = 66.5 in3)
