The sphericаl fаce shield оf аn astrоnaut's helmet is made frоm polycarbonate with a yield strength of 116 MPa. The shield has an outside diameter of 352 mm and a thickness of 4.6 mm. If the shield is successfully pressure tested to 915 kPa on Earth, determine the factor of safety with respect to yielding.
