A flywheel is made up of steel ring 40mm thick and 200mm wide plate with mean diameter of 2 metres. If initially the flywheel is rotating at 300r.p.m. Find the time taken by the wheel in coming to rest due to frictional couple of 100N.m. Take mass density of the steel as 7900kg/m3. Neglect the effect of the spokes
