I understand that nothing--object or influence--can travel faster than c. However, something isn't quite clear to me.
Let's assume we have a solid rod or a cylinder that has any given radius and a light-year in length. If the cylinder is at first at rest, and then we apply a torque to this cylinder at one end, thus giving it angular acceleration, will it take a year for the other end of the cylinder to experience the angular acceleration?
