given diameter is $2$inch, L$=2$inch, material is A$36$ steel and F$=150$kip, factor of safety against yielding falure is $2.$ Find normal and shear stresses at point A of the base $,$ determine the in$-$plane principal stresses, determine the critical load for which the system will fail by buckling, and use the maximum distortion energy theory to determine if the system buckles$/$fails
