An aircraft cabin window of circular cross section and simple supports all around as shown in the following is made of polycarbonate with E = 0:345 ? 10⁶ psi, n = 0:36, radius = 20 in., and thickness t = 0:75 in. The safety of the material is tested at a uniform pressure of 10 psi. Determine the maximum deflection and maximum principal stress in the material. The yield strength of the material is 9 ksi. Comment on the potential use of this material in regard to strength and deflection.
