Question
A hemispherical window (or viewport) in a
decompression chamber (see figure) is subjected to
an internal air pressure of 85 psi. The window is
attached to the wall of the chamber by 14 bolts.
(a) Find the tensile force F in each bolt and the tensile
stress s in the viewport if the radius of the
hemisphere is 14 in. and its thickness is 1.25 in.
(b) If the yield stress for each of the 14 bolts is
50 ksi and the factor of safety is 3.0, find the
required bolt diameter.
(c) If the stress in the viewport is limited to 500 psi,
find the required radius of the hemisphere.
