An aircraft cabin window of circular cross section and simple supports all around as shown in Figure P12–10 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.
