Chapter 8, Problem 34P

8-33 to 8-36 The figure illustrates the non-permanent connection of a steel cylinder head to a grade 30 cast- iron pressure vessel using N bolts. A confined gasket seal has an effective sealing diameter D. The cylinder stores gas at a maximum pressure p_g. For the specifications given in the table for the specific problem assigned, select a suitable bolt length from the preferred sizes in Table A-17, then determine the yielding factor of safety n_p, the load factor n_L, and the joint separation factor n₀.
