> 1 g pulling us down as we evolved to handle, but also 1/6 g pulling us sideways. Look at the design, with the surface not vertical but at a steep angle inward. It's pretty clearly designed to produce a total perceived weight equivalent to 1g, composed of 1/6 g downwards caused by the moon, and I suppose 5/6 g sideways caused by rotation. The floor is at an angle that works with the sum of these forces. Having said that, "spin gravity" isn't always comfortable, it depends on how large and how fast it is: https://space.stackexchange.com/questions/9575/mitigating-nausea-when-generating-artificial-gravity-by-centrifuge https://space.stackexchange.com/questions/9575/mitigating-na... This structure looks easily big enough to be out of danger, at 3rpm and 100m radius.
