The sphericаl fаce shield оf аn astrоnaut's helmet is made frоm polycarbonate with a yield strength of 114 MPa. The shield has an outside diameter of 354 mm and a thickness of 5.0 mm. If the shield is successfully pressure tested to 925 kPa on Earth, determine the factor of safety with respect to yielding.
