Shear plane — where it appears
2 essays name this object, across one field. What follows is each of them, and the objects they name alongside it.
The metal between the holes, which comes out as a block
A bolted end connection can fail without a single bolt breaking and without the plate reaching its tensile strength anywhere. A block of metal simply comes out, bounded by two surfaces with two different strengths on them.
The tear that goes diagonally, and the correction that has no derivation
Stagger the holes so that no straight line crosses more than one and the plate does not get its strength back. The tear runs at an angle instead, and the arithmetic that makes it come out right is a century-old piece of curve-fitting nobody has improved on.
