Practice A steel cylinder head is connected to a grade 30 cast iron pressure vessel using 10 bolts. A confined gasket seal has an effective diameter of 100 mm . The cylinder stores gas at a maximum pressure of 6 MPa . Select a suitable bolt length, assuming bolts are available in the increments of 6.35 mm and 5 mm . Then, determine the yielding factor of safety, the load factor, and the joint separation factor. Use M12 \( \times 1.75 \) ISO 9.8 hexagon head bolt.
