[Diy_efi] OT: tubular steel/space frame stress calcs

[Mr. Goat]

The Machinery Handbook will give you all the formulas that you need for
basic hand calcs. In terms of FEA...any respectable package will do an
analysis...look into programs such as Algor or Ansys as they are geared more
towards structural analysis.

Cheers,
M.
