Clarified gravity range.

| Jun 8, 2021 at 18:18 | comment | added | Clockwork-Muse | I seriously doubt non-electric cars would be allowed inside the O'Neill cylinder in the first place, so any cars would also not pollute the air (the difference being they require batteries of some sort). It's entirely conceivable that there are at least some off-track vehicles of various sorts (farming equipment, at a minimum, various emergency vehicles), so the question is still relevant. | |

| Jun 7, 2021 at 17:49 | comment | added | Paul Sinclair | The gravity experienced varies with the square of the angular velocity. So as PcMan indicates, changing your own angular velocity by $\pm10\%$ of the station's would result in the gee-force on you either decreasing to $81\%$ or increasing to $121\%$ of normal (I assume PcMan actually used $440 \pm 40$ mph, not $\pm 10\%$). | |
| Jun 7, 2021 at 11:01 | comment | added | Peter Cordes | @rek: Yes, exactly. 1.0g +- 10% spans a range of 90% to 110% of Earth standard gravity. I think the phrasing is pretty clear that it's talking about deviations from an existing apparent gravity, for a range of horizontal speeds. (Possibly I just got lucky and interpreted it the right way by chance when I first read it, but on re-reading I disagree that it's confusing. If you skimmed too fast, then maybe you'd miss something, but if so you can read that one sentence. And clearly nothing is going to create -10% negative total absolute apparent gravitation, i.e. inward pull from moving.) | |

| Jun 6, 2021 at 23:22 | comment | added | PcMan | I threw numbers at my calculator, it says 82% and 121% actually. Still not at all significant. JUst dont ascend or descend relative to the axis, without some serious precautions. | |
| Jun 6, 2021 at 22:10 | comment | added | rek | That's confusing phrasing; +/- 10% of Earth gravity is 1/10*g* not 90-110%. | |
| Jun 6, 2021 at 18:00 | comment | added | IronEagle | @rek - Yes? Perhaps the +/- 10% is unclear, driving would mean 110 to 90% of a standard earth gravity. | |
| Jun 6, 2021 at 17:58 | comment | added | rek | The wikipedia page says "At the radius described by O'Neill, the habitats would have to rotate about twenty-eight times an hour to simulate a standard Earth gravity; an angular velocity of 2.8 degrees per second." | |
