<p> <\/p><p>I have read about the RRF and MRF. For my case, it is to solve the equation of motion in the IR Reference frame (which rotates with the IR in mechanical).<\/p><p>But the Ball will still translate and rotate w.r.t Inner Race referece Frame. (as the Cage is not present in my case to translate the ball)<\/p><p>Outer Race will move in the opposite direction w.r.t Inner Race reference Frame.<\/p><p>In the Pciture below, The Cage (w_c) rotating casuses the ball to translate\/guide along the circumferece.
