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 pg. 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,, the load factor ₁, and the joint
separation factor no.
