An 18-kip centric load is applied to a rectangular sawn
Chapter 10, Problem 10.72(choose chapter or problem)
An 18-kip centric load is applied to a rectangular sawn lumber column of 22-ft effective length. Using lumber for which the adjusted allowable stress for compression parallel to the grain is \(\sigma_{C}=1050 \mathrm{psi}\) and the adjusted modulus is \(E=440 \times 10^{3} \mathrm{psi}\), determine the smallest cross section that can be used. Use b = 2d.
