The figure illustrates the 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 np, the load factor nL, and the joint separation factor n0.

A ............. 20 mm
B ............. 20 mm
C ............. 100 mm
D ............. 150 mm
E ............. 200 mm
F ............. 300 mm
N ............. 10
pg 6 ............ MPa
Bolt grade ........... ISO 9.8
Bolt spec. .......... M12 × 1.75
