The purpose of this exercise is to examine how stresses evolve within the walls of a pressure vessel as a function of position within the wall and wall thickness. Recall the thick-walled cylinder solution developed in class. Re-write the solution to the case of a thick-walled cylinder with inner radius a, outer radius b, internal pressure p₁, and external pressure, p2.

(b) Make the assumption that p₂ = 0, a + b ≈ 2r, ba≈t, and a b≈r to derive the expression for orr and one for a thin-walled pressure vessel. For a sanity check, your solution should be arr 0 and σ00 = pir/t. = (c) Now consider the classical strength of materials approach to pressure vessels.
