Question:

A long strip of paper is wrapped into two rolls, each having mass M. Roll A is pin-supported about its center whereas roll B is not centrally supported. If B is brought into contact with A and released from rest, determine the initial tension in the paper between the rolls and the angular acceleration of each roll. For the calculation, assume the rolls to be approximated by cylinders.
