An undersea research vehicle has a spherical pressure hull 1.2-m radius. The pressure hull is steel having a yield point of 750 MPa. If the allowable depth of submergence is not to exceed 4.3 km, determine the allowable thickness of the hull. Consider sea water to have specific weight of 10.27 kN/m.
