8.8 The spherical gas tank is made of steel (E = 29 × 106 psi, v = 0.3). The inner radius of the tank is 20 ft and its wall thickness is 1.0 in. (a) If the working stress of the steel is 9000 psi, determine the maximum safe pressure for the tank. (b) Compute the corresponding change in the volume of the tank.
