The last sentence was needlessly insulting (it suggests the Spaceman has a
learning problem). I should point out that this newsgroup is open to
people
of all ages and educational attainments from around the world who can read
and write English. It may be that Spaceman has not yet (or never) had an
introductory physics class, but does have a strong interest in science. Or
simply made some mistakes which, had they been pointed out more
diplomatically, been educational rather than confrontational.

Well,
Thanks for seeing that Jim.
Let it be known I have had basic physics classes, and I do know
any mass will increase the total mass.
I also have a good background history in mechanics and have worked
on everything from my hobby of radio controlled cars I build myself
including even putting a dampening oil in the shock absorber during the
build all the way to large trucks such as basic 18 wheelers and also
such equipent as Front End Loaders and such.
A mechanic has no actual size limits.
mechanics basics work in every size.
Scaling is the only change but a lever is still a lever no matter
how big or small it is and a gear is a gear etc..
:)

What of a buckytube one meter in radius? Or merely one millimeter in
radius? I know I'd have to look up the strength of, say, graphite at least
and consult one of my strength of materials text to make sure I was using
the correct equation for stress on a diametral section.

I would love to see such figures.

I know it sounds too simple to be true, but mechanically,
a gas inside that is under low pressure can only increase
the structures ability to withstand outside forces, that is why
I was thinking of such filling with gas and not just vacuum alone.
:)
A simple thought of such would be something like:
Crushing a ping pong ball would be far more easy if it was
a vacuum inside and not filled with air.
