Answer to Question #306362 in Mechanical Engineering for Fareed Askul

Question

(a) A steel tube is shrunk on to another steel tube to form a compound cylinder 60mm internal diameter, 180mm external diameter. The internal radial compressive stress at the 120mm common diameter is 30M N/m². Calculate the shrinkage allowance. E = 200 G N/m²

(b) If the compound cylinder is now subjected to an internal pressure of 25 M N/m². Calculate the resultant hoop stresses at the internal and external surfaces of the compound cylinder.
