Problem 2 10 pts A cylindrical pressure vessel with wall thickness t-5 mm and inside radius r 150 mm is design to hold high pressure. The vessel design requires a safety factor against yielding Xo -2, and leak-before-break with a safety factor X-5 on the critical crack length; that is, the critical crack length ce must be at least Xt. Calculate the maximum pressure, p, if the vessel is...
