In the following problem, unless otherwise noted, assume for steel that the modulus of elasticity is 30,000 ksi (207 × 103 MPa), the proportional limit is 48 ksi (331 MPa), and the yield stress is 50 ksi (345 MPa).
A W12 × 22 structural steel wide-flange section is used as an axially loaded column. Determine the allowable axial compressive load using Euler’s formula and a factor of safety of 2.0. The column is pin connected at both ends and is 14 ft long.
