airplane construction

Cessna uses a bolt installed in shear through fittings like
you fingers meshed. This is called "double shear" and as
long as the bolt is a snug fit in the hole the bolt can hold
more load than the airplane is designed to experience.
But a bolt in tension is stronger than a bolt in shear.



But you don't want to be standing under the wing if someone jerks the stut
off.

Boink!!!

When immigration is outlawed, only outlaws will immigrate.

Without the strut, which is in tension during normal flight
and compression when at less than zero G, the wing would
just flap up and down.

The close fit of the bolts in shear is required so that
loads are transferred evenly to the structure.The torque on
the shear bolts is minimal and the nut just serves to keep
the bolt from falling off/out.
A bolt in tension is torqued so that the bolt is loaded into
the elastic range and the tight bolt is stretched very
slightly and then, as long as the bolt stays tight, it does
not accumulate stress until the loads exceed the elastic
limit.
