Hi Dan,
If you want to get beyond "rule-of-thumb" or conservative
"one-size-fits-all" guidelines, you might want to check out "Analysis and
Design of Flight Vehicle Structures" by E.F. Bruhn. This will show you how
to calculate the strength of any joint with the loads it is expected to see
and predict, for example, if a rivet will fail or the metal will tear out
when a riveted connection reaches its maximum load carrying ability. The
Hiscocks book "Design of Light Aircraft" that Murphy sells is a good start
at getting approximate loads data, as well as how to do overall airplane
analysis.
I applaud the questions you are asking since in my opinion they truly fit
into the spirit of learning that the was the basis for the homebuilder
movement and the reason there is a special category in the regs for
experimental aircraft. As always, we shouldn't do anything critical without
checking with the designer. Only he/she knows the actual loads and design
margins and the failure mechanisms and design philosophy for that particular
design. If necessary, he can custom calculate any joint to see if there is
sufficient excess carrying capacity to permit fudging the cookbook numbers.
But it is very educational and fun to peek beneath the covers and try to
understand why things are done the way they are.

Subject: I need a book reference
Hello!
The following is an excerpt from my correspondence with Murphy Aircraft.
I'd
like to know where I could get such a book. Haven't seen it in Sport
Aviation.
I already have AC 43.13-1A CHANGE 3 AND -2A COMBINED:
People have told me that I don't need the 2D edge distance requirement for
rivets placed such that only a minimal force will be applied in the edge
direction. Specifically concerning the torque tube collar and end plug. I
mentioned this in an earlier email. Where can I get such rules? I didn't
see
any in the books I have.
Hi Dan;
The E.D. on thicker material is not as critical on the thicker materials ,
for example , all of our torque tube horns etc. are common, so the E.D. on
your parts is acceptable . EAA sells a very good book on sheet metal for
A/C
in which all of this information is covered , I can't remember the name of,
but they advertise it the back of their Mags.
Thanks,
Dan
