Re: [PSUBS-MAILIST] Support braces for the Hull

Graham,

While MANNED SUBMERSIBLES is great definitive work, it doesn't address the
specifics of determining Collapse Depth-related internal hull-bracing
requirements.

But the other day you said you'd already calculated the Collapse Depth of
your hull with 3" x 1/2" ribs every 18 inches; why not use the formula you
used then?

And while we're on the subject, would you please share your C-D formula with
the Discussion Group?

Pat
