ante y se IN.. is). Pressure vessels are very common in many industries. 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. Orr σαθ a²p₁b²p2 (6² - a²) a²p₁-b²p2 (6²-a²) axis + 1 (a) Draw a diagram showing the evolution of orr and σ00 from a to b when a/b=0.5 and P2 = 0.

For a sanity check, your solution should be orr = 0 and 000 = pir/t. t (c) Now consider the classical strength of materials approach to pressure vessels. Imagine the pressure vessel shown in Fig. 2 (note, the radius of…
