9.1 (A). Determine the hoop and longitudinal stresses set up in a thin boiler shell of circular cross-section, 5m long and of 1.3 m internal diameter when the internal pressure reaches a value of 2.4 bar (240 kN/m). What will then be its change in diameter? The wall thickness of the boiler is 25 mm. E = 210 GN/m; v = 0.3. [6.24, 3.12 MN/m²; 0.033 mm.]
