A mild steel cover plate is to be designed for an inspection hole in the shell of a pressure
vessel. The hole is 120 mm in diameter and the pressure inside the vessel is 6 N/mm2
.
Design the cover plate along with the bolts. Assume allowable tensile stress for mild steel
as 60 MPa and for bolt material as 40 MPa
