Thanks. You might as well check the original entry here: Measure load-bearing capacity in SU - #14 by endlessfix since there are more answers and scenarios there in the original posting.
One would think, however, that some sort of “Materials” A.I. would be able to calculate load variables for a given span in 1G environments. That is, if a beam made of X (concrete/steel, whatever) is stretched over Y distance, what is the Z weight it can support before bending? I am simplifying greatly, but only in degree, I think, and that’s what powerful computers are for.
