A thin cylindrical shell of diameter d and thickness t is subjected to an internal pressure P. The Poisson’s ratio is v. The ratio of longitudinal strain to volumetric strain is
1
\(\frac{{1 - v}}{{2 - v}}\)
2
\(\frac{{2 - v}}{{1 - v}}\)
3
\(\frac{{1 - 2v}}{{3 - 4v}}\)
4
\(\frac{{1 - 2v}}{{5 - 4v}}\)
