| Subject: | Re: Simple rivet test/unzip |
Well, my test was VERY unscientific, however ...
You are right, it was essentially in tension. But, the heads tear off so
easily, I was very unhappy. I repeated my simple test with A5's, and the
ball end pulls through, but the heads do not pop off. This to my mind
is ok. The rivets themself don't just break in half.
Regards,
Jeff

piece? Or, was the rivet in shear or tension. Would expect the rivet heads
to pop off if your tug was 90 degrees to the clamped part but if it was 180 degrees
then there is a problem. Jerry of Ga DO NOT ARCHIVE

>From Alex's picture, it seems like the control rod is holding the aileron but
the air is pushing up on the aileron at the aileron hinge portion and causing
the kink we see.
What force would that primarily be, tension or shear? Tension, correct?
That large gap between the aileron and wing always looked funny when parked in
a car next to the aircraft. Could it be that since the gap is no longer sealed
by the hinge-less aileron skin, some sort of turbulence or pressure is created
between the forward edge of the aileron and the rear spar, causing this flexing?
The fact that the flexing is only noticeable at the inboard or next rib and not
the outboard ribs seems to indicate that the control rod has some influence on
the action.
Please don't write to me at my @msn account. PM or write it here. Thanx
