Hello on page 167 of the Pressure Vessel Design Handbook by Bednar in the example for designing support lugs he references a formula to calculate the allowable compressive stress for the gusset.
"Sa=18,000/(1+1/18,000*(L/r)^2)=9,885 psi"
I cannot find reference to this formula in any structural analysis texts and unless I am missing something the units do not work out. Does anyone know where this formula comes from and why the units don't seem to work?
Regards,
Alex
