QUESTION 3 a) A thick-walled pressure vessel (Figure 3) of internal radius 1.0 m, external radius 1.2 m subjected to an internal gauge pressure of p = 30 MPa. Determine the change in internal radius of the vessel due to this pressure. Assume it is open ended and made from a steel with E = 200 GPa, v = 0.3. b) What are the principal strains at the inner radius? b Figure 3 P
