Assume Wheel is at Earth Sea Level + 3 Meters.
Assume wheel axis is vertical.
Assume wheel is a 1" dia. torus some 3 foot in overall diameter.
Assume spin rate at some 3 Million RPM.
Pick a point on the torus and it will be travelling better than escape velocity relative to the Earth and will want to fly off tangentally into space.
Calculate the theoretical uplift or +Y force on the Torus.
Now calculate the effect on the local space time field.

Oh yes, assume a weight of the Torus of say 1 Kilogram.

wow....I have absolutely NO clue! is this a real question or just way out of my field? a spinning wheel floating on a bent space time field....gee.

If I'm to interpret that to mean that the tangential velocity is equal to orbital escape velocity on earth, that would indeed warp space and time (just like any other motion) but it would not be NEAR enough to cause any real relativistic phenomena.

Even if you were to spin it at 90% of the speed of light, it wouldn't suddenly start floating. In fact, as it aquired more energy, its gravitational attraction to the earth would increase.

No because the wheel is spinning at escape velocity in relation to itself. When spacecraft travel at escape velocity it is measured in relation to the earth. Therefore the wheel is really travelling at 0 meters per second relative to the earth. (This being the only factor in escaping the pull of earth's gravity)

No. Space-time will be bent somewhat by the mass of the wheel, but orbital escape velocity is so far smaller than the speed of light that relativistic effects will not be seen.

yes, in my world, anything's possible.
