A cylindrical vessel whose ends are closed by means of rigid flange plate is made of steel plate 3 mm thick. The internal length and diameter of vessel are 50 cm and 25 cm respectively. Determine the longitudinal and circumferential stresses in the cylindrical shell due to an internal fluid pressure of 3 MN/m2. Also Calculate increase in length, diameter and volume of the vessel. Take E = 200 GN/m2, and 1/m = 0.3
