    Annular steel rotating flywheel 500mm diameter and 60mm wide is supported on a steel shaft 100mm diameter and 100mm long rotates at 2000 rpm. If the shaft bearings induce a frictional torque equivalent to 40Nm, how long will it for the flywheel to come to rest if the density of the steel is 7850kg/m3.
