Bolt tension — 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 force the bolt never saw applied
Pull a tee stub with a hundred kilonewtons and its bolt carries a hundred and fifty. The extra comes from the flange bending and pressing its own edge against the thing it is bolted to, and no free body of the connection as a point contains it.
The joint that carries nothing until it slips
Tighten the bolts hard enough and the plates are clamped together with a force nothing applied. The joint then carries shear by friction, the bolts are in tension and not in shear at all, and the load path has nothing in common with the joint it looks identical to.
