A cleaning machine presses a circular mop of radius R= 30 cm vertically down on a floorwith a total force F = 25N and rotates it with a constant angular speed about the verticalaxis passıng through the centro of mop. If the force is distributed uniformly over the mopand if the coefficient of friction between the mop and the floor is u=0.25, what is thevalue of torque in N - cm applied by the machine on the mop?
