Question
A spherical steel pressure vessel (diameter
500 mm, thickness 10 mm) is coated with brittle lacquer
that cracks when the strain reaches 150 X 10-6
(see figure).
(a) What internal pressure p will cause the lacquer
to develop cracks? (Assume E = 205 GPa and
v = 0.30.)
(b) If the strain is measured at 125 X 10-6, what is
the internal pressure at that point?
