For educational purposes I did some shear and tensile tests with the 3.2 and 4.0 mm rivets.

After digging a bit more into bolts and nuts a learned that torque isn’t tension.

I was curious about how strong the aviation grade bolts are. With help from the University in Delft at the faculty of Aerospace Engineering I did some tension tests.
