Question
The load P acting on the steel cantilever column has an eccentricity e = 15 mm. with respect to the z-axis. Determine the maximum allowable value of P using a factor of safety of 2.5 against yielding and buckling. Which failure mode governs the solution? The material properties are E = 200 GPa and Gyp = 250 MPa.

Question
The structural steel column shown in figure below is fixed at its base and free at its upper end. At the top of the column, a load P = (15 + 0.05R) kip is applied to the stiffened seat support at an eccentricity of e = 9in from the cross-sectional x-axis of the I-section shape. Analyze using the AISC equations and allowable stress method to determine whether the column is safe under the applied eccentric load. Assume E = 29000 ksi and sigma_{y} = 36ksi The area of cross-section A = 10.45i * n ^ 2 the moments of inertia I = 122.671 in and 1=42.692in of the I-section.
