>>11414401>roche limitKind of irrelevant considering that the orbital ring isnt reliant on its own gravity to stay together
>wave propagationthere's plenty of ways to damp that enough (probably in such a way to tap for energy too) to make anything significant build up
>extra planetary tidal forcesthe "orbit" of the accelerated material is also warped by this, in such away that the change in centrifugal force exerted still cancels with the weight of the stationary part.
>solar phase declination partice flux cumulative chargingwe can deal with that in modern spacecraft, and on something with so much potential mass, it's not too tricky to generate a big enough net current that no major charge builds up.
>linear mass acceleration shear forceiirc, none of the components of the orbital ring need to be solid, while it could be a bit of a pain from an engineering perspective, it's not a concept destroying issue.
>metal fatigue due to temperature fluctuationsweird argument, and is also an engineering issue (and may also be negated for the same reasons as for the previous bit). I'll agree that, for a solid ring, it would be a major pain in the ass to keep things heated/cooled uniformly for most rings (though still entirely possible). One way to just completely ignore this, is to put the ring into a sun synchronous orbit, such that no region of the stationary part of it ever goes from dark/light or vice versa.
>basal shear stressI struggle to see how this is super relevant, unless you've got some funky eccentricities going on, and even then that's only for a solid ring.
>secular & periodic gravitational pertubation>constant orbital degradation & related forcesI doubt that these would be severe enough that it couldn't be manually corrected, and even then they may be slow acting enough that lateral forces from the orbital part may nudge the stationary along with it.
Overall, fuck knows about their viability without running the numbers, but none of those rule them out.
