Question: answer is 384 mpa please show me the working...

Question details

The figure shows the connection of a cylinder head to a pressure vessel using 20 bolts and a confined-gasket seal. The effective sealing diameter is 150 mm. The bolts are M10, grade 8.8. 0 Cylinder head is steel, E 207 GPa, Cylinder is cast iron, E 113 GPa Given that the joint stiffness is 1200 kN/mm, the bolt stiffness is 360 kN/mm and the bolt is pre-tensioned to 75% of proof load (reusable), at what pressure will the joint leak? -20 25-
Answer is: 38.4 MPa - please show me the working on how to get this answer?
