I'm doing a bit of research for a story, so let me apologize in advance

if this doesn't fit the mandate of your groups. I won't repost if I

don't get an answer. Thank you, though, for your time in advance.

I'm trying to find a formula or a chart that'll help me figure out

average/ideal steel strengths given a bar of a certain diameter. For

instance, how thick of a rod of steel would a person need to keep it

from buckling when a super-human applied a ton of pressure. I realize

there are different types of steel, purities, etc., which is why I

thought there might be a kind of slide-rule-esque chart for figuring

X-type for Y-weight is Z-thickness.

Any help would be appreciated. I've Googled and checked Wikipedia, but

the best they seem to have is related tooling equipment and melting

points, respectively, which is interesting but not what I need. Again,

thank you in advance for your help!
