A cylinder pressure vessel 10 m long has closed ends, a wall thickness of 5 mm, and a diameter at mid-thickness of 3 mm. If the vessel is filled with air to a pressure of 2 MPa, how much do the length, diameter, and wall thickness change, and in each case state whether the change is an increase or a decrease. The vessel is made of a steel having elastic modulus E = 200,000 MPa and the Poisson’s ratio ? = 0.3. Neglect any effects associated with the details of how the ends are attached.
