On the Cessna I don't remember how many "wing nuts" there were holding

attaches to the body. There must be insane amounts of stress on that
small area of metal.

Most of the lift is transferred via the struts, not at the wing root (now
I'll be darned if I can remeber where I read that...). The wing basically
pulls on the strut, and the wing root only has to keep it from tipping one
way or another.

Anno.
