For the cylindrical vessel with ellipsoidal heads shown in Figure P9–22a under loading p = 500 psi,.


For the cylindrical vessel after a while ellipsoidal leaders shown in Figure P9–22a beneath loading p = 500 psi, particularize if the vessel is safe against producing. Use the corresponding representative and rudiment of protection as in Problem 9.21. Now let a = 100 in. and b = 50 in. Which vessel has the smallest hoop stress? Recommend the preferred leader cast of the two domiciled on your answers.

For modeling purposes, the equation of an omission is given by b2x2 + a2y2 = a2b2, where a is the elder axis and b is the younger axis of the omission shown in Figure P9–22(b).
