That is fascinating Bud and I have actually reviewed it before. Somehow
though I have missed the section on the stress analysis of a steel tube
fuselage.

The books recommended by myself and others are primers. As such they
give the reader the needed context of where to apply a euler equation to
an airframe and how to apply it.
