The spherical face shield of an astronaut’s helmet is made from polycarbonate with a yield strength of 105 MPa. The shield has an outside diameter of 358 mm and a thickness of 4.3 mm. If the shield is successfully pressure tested to 840 kPa on Earth, determine the factor of safety with respect to yielding.

The spherical face shield of an astronaut’s helmet is made from polycarbonate with a yield strength of 101 MPa. The shield has an outside diameter of 350 mm and a thickness of 4.1 mm. If the shield is successfully pressure tested to 835 kPa on Earth, determine the factor of safety with respect to yielding.

The spherical face shield of an astronaut’s helmet is made from polycarbonate with a yield strength of 107 MPa. The shield has an outside diameter of 354 mm and a thickness of 4.7 mm. If the shield is successfully pressure tested to 940 kPa on Earth, determine the factor of safety with respect to yielding.
