As the contact is frictionless, one cylinder can rotate freely with respect other. The displacement in tangential directions need not be same at a point contact for two cylinders Similarly the Hoop stress at point of contact need not be same As the interface will be always in contact the displacement in radial direction and stress in radial directions must be same for two cylinders. i.e.,
