Two flywheel 48 in the form of disks of the same radii and masses are unwound to the speed of rotation of 480 rev / min and left to themselves. Under the action of the friction forces on the shaft bearings through the first stop 80, and the second made 240 rpm to a stop. Which flywheel friction torque on the shaft bearings has been more and how many times?
