An aircraft cabin window of circular cross section and simple supports all around as shown in Figure
An aircraft imprison window of spherical ill-conditioned minority and simple supports all environing as shown in Figure P12–10 is made of polycarbonate with E = 0:345 106 psi, n = 0:36, radius = 20 in., and besottedness t = 0:75 in. The protection of the embodied is tested at a uniform pressure of 10 psi. Determine the ultimatum swerving and ultimatum principal stress in the embodied. The concede ability of the embodied is 9 ksi. Comment on the virtual use of this embodied in value to ability and swerving.
