Torque and angular acceleration of a ring and bar combination.

A uniform thin ring, mass M= 6 kg and radius R= .35 m, with a bar of mass m= 4.5 kg across its diameter, is mounted on frictionless bearings at its center. A cord wrapped on the surface of the ring suspends a weight W= 14.7 nt. See ATTACHMENT1 for a diagram showing parameters and stating physics required.
