When the internal pressure load remains unchanged, the maximum hoop stress in the inner cylinder of the compound cylinder has been found to be reduced by 5% of the original value (i) Calculate the interface pressure at the common radius of the compound cylinder. (ii) Assume the cylinders are made of a copper alloy. Suggest alternative ways to increase the FOS and discuss whether the compound solution is better.
