Let’s say you’re riding one of those gravitron rides that are common at carnivals but this one is different. It’s a gravitron inside a gravitron and you’re in the inner gravitron. The outer gravitron spins clockwise and the inner gravitron along with it fast enough so that you feel 3 G’s of force. While the outer gravitron is spinning clockwise the inner gravitron begins to spin counter clockwise fast enough to simulate 3 G’s of force. Since the inner gravitron is spinning the opposite direction as the outer gravitron would you feel O G’s of force or 6 G’s of force?
Follow up question if the force is doubled. You have the outer platform spinning one direction and the inner platform spinning the opposite direction at the same speed. Relative to the earth it would look like the person riding the inner platform is standing still. Could anti gravity be simulated by tilting the ride 90° so that the rider is constantly facing the ground while feeling 6 G’s of force pushing him upward?

Yes, but not for long.
Centrifugal force is caused by your trajectory being redirected out of the normal straight line trajectory.
So when you turn in circle you constantly get redirected to the same side, and that’s why you feel an acceleration in the opposite direction. If you manage to be in a spot where the two spinning things cancel out and you go in a straight line, it don’t move, then you will feel no acceleration.
Unfortunately, in the design you described you will eventually reach the end of the outer gravitron, and that’s where the two nested gravitron will work together to accelerate you towards the center, and you will suffer lots of G.
