Thanks for the correction, Unclenick - when I was balancing the gravitational force against the centrifugal "force", I switched units from Newtons to kilogram-force midway through the calculations. So my final answer was off by a factor of sqrt (9.81).

Serves me right for not "stink checking" my answer - 240 rpm should have seemed excessive to me.
