I am looking over some proposed rotating spacecraft such as the Nautilus-X and the Ares from the movie The Martian as well as much more fictional ones such as from the Jovian Chronicles and even Halo.
My question is, would not these spacecraft have a tendency to flip because of the Tennis Racket effect?
And while moving these spacecraft (if they started thrusting) wouldn't inhabitants of the wheel/ring be thrown to the sides of the wheel while it was moving?
