A compound cylinder is made by shrinking a jacket with an outer diameter of 200 mm on a hollow cylinder with diameter of 100 mm and 150 mm. When the compound cylinder is subjected to an internal pressure of 35MNm-2, the maximum circumferential stress in both cylinders is the same. Calculate the maximum stress developed at the internal diameter of the jacket.
