I remember from reading about O'Neill cylinders that an object spinning on it's long axis will, under the influence of random perturbation, eventually start tumbling. So I'm wondering, if we take Oumuamua's angular momentum and figure out the rate of axial spin required to get the same angular momentum, do you get anything like earth-gravity equivalent centrifugal force near the surface of the object?

If it's 400 meters long and do one rotation in 7 hours the gravity is essentially zero. It'd have to rotate twice per minute to produce 1g.

Why earth gravity?
