| Jul 21, 2017 at 22:35 | comment | added | Mazura | @Vashu - I figured we were to assume that it can take that stress, and that it 'magically' 'supports' itself (with engines or something to keep it in the right place. Which you'd need, so I don't know why we aren't just strapping an engine on it also to spin it). It's an interesting thought experiment, except I'd expect anyone who understands the CoAM to also at least grasp the basics of orbital mechanics... | |
| Jul 11, 2017 at 2:24 | comment | added | Vashu | Yes, it would. But mechanical stress on cables would be enormous - about weight of half of the ring multiplied on acceleration. It would work if structure is more complex - internal ring spins fast and supports slower external ring that has gravity. | |

| Jul 10, 2017 at 21:37 | comment | added | wetcircuit | Yes, it was intended as a planet. | |
| Jul 10, 2017 at 21:28 | comment | added | Harry Johnston | Is that circle in the middle of the diagram the planet? | |

| Jul 10, 2017 at 20:48 | comment | added | wetcircuit | @ozone, yes, I think that is correct. Energy has to be ADDED to the ring's spin, not just re-arranged. | |
| Jul 10, 2017 at 20:43 | comment | added | ozone | If the habitat spun faster than is required at it's orbital altitude, wouldn't that create the artificial gravity he is after? It does seem like just reducing the radius may not be enough, but if he increased the rotational velocity with thrusters or something, wouldn't that work assuming the ring could handle the stresses? | |

| Jul 10, 2017 at 16:07 | comment | added | Isaac Kotlicky | Assuming you're starting with a low-g habitat: Well, as your sections are winched together they are ALSO getting closer to the planet, so their faster spin would be counteracted by a stronger pull from the planet, netting out to zero or near zero change in gravity. (IANAPhysicist, this is just my best guess.) | |
