The pressure hull of a space station module has an inside diameter of 4.7 m, a length of 5.4 m, and a wall thickness of 2.5 mm. It is made from an aluminum alloy with a yield strength of 247 MPa. If the hull is successfully pressure tested to 155 kPa on Earth, determine the factor of safety with respect to yielding.
