The spherical face shield of an astronaut’s helmet is made from polycarbonate with a yield strength of 104 MPa. The shield has an outside diameter of 351 mm and a thickness of 5.4 mm. If the shield is successfully pressure tested to 920 kPa on Earth, determine the factor of safety with respect to yielding.
