A 57.5-kg grindstone is a solid disk 0.6 m in diameter. You press an ax down on the rim with a normal force of 164.9 N. m The coefficient of kinetic friction between the blade and the stone is 0.7, and there is a constant friction torque of 9.5 N m between the axle of the stone and its bearings. Another force is applied tangentially at the end of a crank handle 0.5 m long to bring the stone from rest to 164.1 rev/min in 8.1 s.
