```							according to me,the machine which have less radius have greater revolution per min.... because as the radius increases,moment of inertia increases since, moment of inertia is inversely proportional to angular velocity(at constant torque)
so,,,,
the machine which have less radius have greater angular velocity & have greater revolution
