Math Problem Statement
An Airbus A320 with a fuselage diameter of 4 meters is on cruising ilight. The cabin pressure
during flight is set to 2400 meters. If the fuselage is not allowed to expand more than 4.1
meters, determine the minimum thickness of the skin used in the aircraft. Use aluminum with
E = 20 GPA and Poisson's ratio of 0.33. (Give the answer in mm and round of the nearest
hundreds)
