There does not actually exist any symmetry because the motor attached to cylinder P makes it rotate at a specified constant velocity whereas the friction is responsible for making the cylinder Q reach to the constant angular velocity as required in the steady state.

I have now understood that there must be relative motion between the two and the steady state is reached when the direction of frictional force becomes parallel to the axis of Q such that it's angular velocity remains constant. Thank you for your instructive replies.

The wording of the question is correct. I think I am not getting what exactly is happening at the contact point. In steady state there should not be any slipping between the surfaces, what will happen to the angular velocities of the cylinders in such a case, please explain??

Homework Statement .A cylinder P of radius rP is being rotated at a constant angular velocity ωP along positive y-axis with the help of a motor about its axis that is fixed. Another cylinder Q of radius rQ free to rotate about its axis that is also fixed is touched with and pressed on P making...
