The built-up cross-section of the 2.0-m, fixed-base column shown below comprises three 300-mm × 25-mm plates that are welded together. The column is subjected to a 300-kN compressive axial load and moments of 100 kN.m and 50 kN.m about the x and y axes, respectively, at its free end (top). Using Fusion 360, compute maximum tensile and compressive stresses (along z) at mid-height of the column (sufficiently far away from stress concentration zones) and compare them with your hand calculations.
