A young engineer has come up with a 'brilliant idea': an aircraft with a square fuselage for more space. Since all aircraft have a circular fuselage cross section you suspect there must be a downside to this plan and you suspect it has to do with stress in the fuselage skin due to the cabin pressure.
To convince the young engineer, you have to determine the 'circular' stress in the fuselage due to the cabin pressure as a function of R,P(in) , P(out) and t . To do so, make use of the figure below.
