Star Destroyer maneuverability

It would be a good lower end but nothing more, maneuvering too hard when in such close proximity to other ships could be a Bad Thing (TM).

Please justify your assumption that the acceleration and consequent maneuverability I've calculated exceed the limits of the structure of the ISD. I know that at some point an arbitrarily high acceleration would overstress the structure. I'm asking you to justify the assumption that this acceleration is beyond that boundary.

Ehh, my reply was lost to minor maintenance and yesterday I wasn't near my computer.

As you can see from the formula, the centripetal acceleration grows over time, without any upper limit. It will overstress any structure with a finite structural strenght, the only question is when.
The stress caused by 13 rad/s2 accelerated turning at 1100 metres from the center will reach 30,000 m/s2 after 0.3766 s, will reach 185,900 m/s2 after 1 second and will grow further ...
(EDIT: After two seconds, it will be 743,737.4873 m/s2, more than a magnitude higher than the stress resulting from the linear aceleration/deceleration.)

I don't know if you were wording things poorly or if my reading comprehension sucked or both, but I didn't get that from your earlier posts. I now understand what you're saying. It would be a concern, I suppose, but not for several seconds of turning at the least (based on the black hole incident among other things).

Sorry. Likely, my writing skills ...
If we knew the stress tolerance, we would be able to count how long it can acelerate the turning before overstressing. (After that aceleration, ihe ISD can maintain that turning speed virtually indefinitely, of course.) Since I do not know it, I assumpted that the stress tolerance of the ISD is the same against both aceleration and deceleration and used the 30,000 m/s2 as a minimum (stress tolerance) value ...
