I have no math and I must scream

[kinzel]

I'm looking for an idea of what kind of rotation I'd need on a drum with a diameter of about 6 meters to give an object/person on the inside of the drum the feeling of 1/10, 1/3, 1/2, 3/4, 1, and 1.5 g ... is that too hard? Alas, I have no math and I must scream. Said drim to be in a spaceship in orbit, if you care.

For many of us travelling in a vehicle not under our ddirect control is always nauseating, no matter how much we do it. It isn't only a visual/motion conflict, blind people get car-sick as well. Indeed, I and many others find that if we can't see it's worse.

Being in control of the vehicle (and even more one's own body) makes it a lot easier to take the movement. In the case of dancers and skaters they deliberately minimise the effects by facing the head in the same direction for as long as possible (except for people in horror movies human heads don't rotate through complete circles, but dancers etc. simulate it so that it almost looks as though they are doing that). Being able to anticipate the movement, and for it to be easily predictable (when I turn the wheel to the left I feel acceleration to the right, etc.) makes it a lot easier to handle.

If one were only lying in the rotating cylinder and only moving to enter and leave then probably there wouldn't be much problem. However, if one were moving around then the Coriolis effects and the change in acceleration would be hard to accustomise, much like inner-ear disorders (I know people who have learned to live with them but none who have eliminated the reaction to sensations). Especially in such as small and quickly-rotating frame of reference the sensations caused by even a small movement would be more than we would expect to handle.
