A flat 6-in. diameter disk buffer shown in P18.3 has a rotation speed of 500 rpm. The coefficient of friction between the buffer disk and a flat metal surface being polished is 0.2. The force on the disk is 15 lb. Assume that the normal pressure created by the 15 lb is uniformly distributed over the surface of the disk and that the tangential pressure force on the disk is q = fp, where f is the coefficient of friction. Determine

(a) the torque to rotate the disk, and

(b) the power transmitted to the buffing disk.
