Problem The figure illustrates the connection of a cylinder head to a pressure vessel using 10 bolts and a confined-gasket seal. The effective sealing diameter is 150 mm. Other dimensions are: A-100, B =200, C=300, D=20, and E = 20, all in millimeters. The cylinder is used to store gas at a static pressure of 6 MPa. ISO class 8.8 bolts with a diameter of 12 mm have been selected. This provides an acceptable bolt spacing. What load factor n results from this selection? Note: Cylinder head material (D) is steel, the cylinder material (E) is cast iron. Assume non- permanent joint, Modulus of Elasticity of the bolt E-207 Gpa. B
