## The Attempt at a Solution

I am bit confused with the boundary conditions of this problem. I understand the radial stress is zero on the inside diameter and the radial stress on the outside diameter will be the reaction to the centripetal force per m^2. So surely you need a width to calculate the radial stress on the outside diameter which isn't given in the question?
