I have a two meter wide cylinder with a diameter of 4 meters. It is vertical to the ground and firmly anchored. I spin it fast enough to hold my body to the outside walls. I am about 100 kilos but that really is not important. I shut it down and get off. I now insert a second cylinder of a lessor diameter say 3.5 meters but same width inside this larger cylinder. This second smaller cylinder is also free wheeling. It is anchored only to the first larger wheel. Looking at the cylinders from the side you can see only the larger cylinder but looking from the front or back you see a smaller cylinder inside a larger cylinder. This can be done and it will be free wheeling. I will not go into the mechanics of how that is done. It is not important to the question. I now rotate the larger wheel to the right once again fast enough to hold me to the side but not so fast as not to allow me movement. Let's say fast enough to have an effect a little greater on me than gravity would if I was standing on the ground. Now I rotate the inner wheel the opposite direction the same speed as the larger outside wheel compensating for the diameter difference. I now am in the inner wheel. I already know I could stand up inside of the inner wheel and not appear to move from ground perspective as the two wheels are going the same speed but in opposite direction and both fast enough to hold me to the cylinder wall. Where I start would not matter. My question is would I be limited to my movement to the original standing location or could I walk around this inner wheel just like I would be walking through a park on a sunny day either direction? I am thinking the latter.
