10.72 An 18-kip centric load is applied to a rectangular sawn lumber col- umn of 22-ft effective length. Using lumber for which the adjusted allowable stress for compression parallel to the grain is ac = 1050 psi and the adjusted modulus is E = 440 x 10' psi, determine the small- est cross section that can be used. Use b = 2d. Fig. P10.72

10.72 An 18-kip centric load is applied to a rectangular sawn lumber col- umn of 22-ft effective length. Using lumber for which the adjusted allowable stress for compression parallel to the grain is ac = 1050 psi and the adjusted modulus is E = 440 x 10’ psi, determine the small- est cross section that can be used. Use b = 2d. Fig. P10.72
