A bicycle wheel (ring) of mass 1kg and radius 2m is attached at the end of a long rod of mass 1kg and length 3m, with the axis of wheel perpendicular to the rod. The rod is rotating counter clockwise as seen from above about its other end with an angular speed 0.5 rad/s. If wheel is also rotating about its axis with same angular speed in counter clock wise sense as seen from above.
