36.6 kips when divided by pi does not come out to 31.06 ksi. It should instead be 11.65 ksi, or thereabouts. I was a little bit confused at first where that number came from but I realized it is what you get when you divide the original computed value for Pcr, 97.57 kips, by pi. I believe this is a mistake.
I wanted to verify this calculation provides a verified factor of safety of 2 for buckling only, correct? We would have to calculate from the original Pcr to have an idea of whether or not the build met an FOS of 2 for yield stress, right? Because if the column failed due to stress at the Pcr value, then stress would control the factor of safety?

The formula used in computing the moment of inertia?........am confused is it not ment to be: 1/64(pi*D**4)
Either equation is correct. 1/64 * pi * d^4 is the same as 1/4 * pi * r^4 since r = d/2
36.6 / pi = 11.65 ksi... am I not seeing how you got 31.06 ksi??
