Figure shows a hollow cylinder of mass M = 1.2 kg and length L = 1.6 m that is free to rotate about a vertical axis through its center. Inside the cylinder are two disks, each of mass 0.4 kg that are tied to a central post by a thin string and separated by a distance l = 0.8 m. The string breaks if the tension exceeds 100 N. Starting from rest, a torque is applied to the system until the string breaks. Assuming the disks are point masses and the radius of the cylinder is negligible, find the amount of work done up to that instant. Suppose that at that instant, the applied torque is removed, and that the walls of the cylinder are frictionless. Obtain an expression for the angular velocity of the system as a function of x for x
