A thick-walled cylindrical tank of inner radius a and outer radius b is made of ASTM A-48 cast iron (see Table D.1) having a modulus of elasticity E and Poisson’s ratio of v. Calculate the maximum radial displacement of the tank, if it is under an internal pressure of p_i, as illustrated in Fig. P8.24. Given: a = 0.5 m, b = 0.8 m, p_i = 60 MPa, E = 70 GPa and v = 0.3.
