2007-present, in this case
People making conclusions should look at the data, though.
In this case, every ciruit has a 64+% reversal rate, the sixth has a reversal rate almost identical to the 9th. I have no idea what a significant difference would be.
Maybe someone can explain a set of assumptions and the resulting variance.
I agree that people should look at the data before making conclusions, which is why I posted that the data directly contradicted GP's claim that the 9th "usually has the lowest, or among the lowest, reversal rate of any district." It doesn't. Based on the data, it has not only the highest reversal rate but also the highest amount of reversals. I take no position on whether the 9th's reversal rate is significantly different than any other circuit's other than to note that it is the highest by all reported metrics and that when you hear that fact, it isn't a "lie" (as characterized by the GP).
Steel is weaker in compression than tension. It's more isotropic than say concrete, but the difference is meaningful in practice.
We're not discussing rupture here. That's for when the pressure is higher internally than externally. We are discussing a submarine, which is a pressure vessel under compression which must also remain buoyant. The specific yield compressive strength is the value which matters.
When I use the word "rupture" I am talking about the material property, not the specific submarine loading condition at play. When comparing steel, which is a ductile material, to carbon fiber, which is a brittle material, you should use the steel's rupture strength instead of yield strength. Steel is for all intents and purposes an isotropic material, and the difference between tensile strength and compressive strength is not material in practice (because steel in compression is nearly always governed by macro-scale geometric issues leading to buckling rather than the material strength in compression being exceeded).
