Euler buckling
2 essays name this object, across one field. What follows is each of them, and the objects they name alongside it.
Also named here as residual stress — the same set of essays touches all of them, so they are one junction rather than several.
Strong enough and still falls over
A column can fail at a fraction of the load its material could carry, by going sideways. Buckling is a failure of stability rather than of strength, and it is decided by geometry.
The column that was never straight
Euler's load is the load at which a perfectly straight column becomes indifferent to being bent. No column is perfectly straight, so no column ever reaches it — and the load it never reaches can still be measured.
