I'm trying to calculate the max load of a rack made of 3X3X1/4 steel tube. It is 8ft long and 4ft wide. I just want to calculate the max load (distributed load) in bending (prob for just the 8ft sides) and also in compression for the legs. i can't find the right formulas. can anyone help?(adsbygoogle = window.adsbygoogle || []).push({});

so far i have

MOI (I)=3.495 in^4

Section modulus=2.330 in^3

MOE (E)=29,000,000 psi ( i think this is correct but i'm not sure. just want to use low grade steel)
