A 1m radius ring thus weighs 6.28kg, it's spinning at 1g, thus 6.28kg of force is trying to pull it apart. 2m ring, 12.56kg of force. 1km ring, 6.28 tons of force. Eventually the force pulling the ring apart snaps it. You can't beef the ring up because that increases the force as much as it makes it stronger. | |
