Do you have any references I could checkout? (note I
quoted my information source for people to check out).

This web page is almost an exact reproduction of
the part of the book I referred to earlier:

http://www.mech.port.ac.uk/CTFR/concept/concept5.htm
(well worth a read BTW)

When I converted the units from SI to psi I did
a search on the web and checked my results against
that published on some web sites, things seemed pretty
close to mine.

However, to answer your first question, NO, I'm not sure,
and I intend conduct some distructive tests to find out.

Ian.
