Acircular steel cylinder of similar external and internal dimension to that in part (a) above, is now made by shrinking a cylinder of external diameter 0.2 m and internal diameter 0.1 m, onto an internal cylinder of similar material with external diameter 0.1 m and internal diameter 0.05 m. determine the radial pressure 'or' at the common surface due to shrinkage alone, so that when there is an internal pressure of 300 mn/m2, the maximum hoop stress σh in the inner cylinder is 150 mn/m2.
