They are not “shear pin” in the way most people understand the term.
They are pins holding the pieces-parts together. They have a failure point (”shear”), like all things do, like rivets and such, but the pins are not designed to fail upon a crash/hard landing. They use pins because of engine changes and deport maintenance.
At what point are you going to design the pin to shear?
How many longitudinal G’s?
How many transverse G’s?
How about speed? Taxi speed when the jet depart the runway and goes into the dirt and gear fails at 50kts in the mud, will it fail then?
Anyway, got to start the BBQ.
See ya.

Personally I have no clue. I’ll have to lean on the guy who used to build the plane, deliver the plane, work on Air Force One, and fly them.
