The pressure hull оf а spаce stаtiоn mоdule has an inside diameter of 4.7 m, a length of 5.5 m, and a wall thickness of 3.0 mm. It is made from an aluminum alloy with a yield strength of 241 MPa. If the hull is successfully pressure tested to 180 kPa on Earth, determine the factor of safety with respect to yielding.
