Hinges under stress - mechanical engineering type question

Corrie wrote:

The largest hinge at AS&S is just 2" wide, and they all seem to have
the same size pin - .089 stainless. That's .006 sq. in. area. I
can't find a reference for shear strength for stainless, but taking an
optimistic SWAG at 200kpsi (the highest yield strength for drawn ss
referenced at http://ourworld.compuserve.com/homep...orhis/T006.htm),
that's 200,000 x .006 = 1200 lbs. Not nearly good enough. /musing



That's 1200 lbs at each hingepoint, that is every place that you could
slip a feeler guage down and touch the pin. That's about every 1/2" or
so on most of these strips.
