You are right, Doug


When it comes to structures like towers you have to take in consideration the buckling effect. Just an extreme example; a long steel wire cable has no strength in compression but all its strength in tension. I am not sure what the story is with the legs in a tower.

Well you are going to have to take that point up with sdsc.edu.

"Metals like steel are elastic materials. Such materials are equally strong
in compression as in tension. ... when subjected to very large forces, it is
much stronger in compression than it is in tension."

I wasn't born in Saskatchewan, but I got here as soon as I could.

Doug,


I have to correct one of your statements: Any metal structure, in general,
is stronger in tension than in compression. This doesn't change your point,
though.
