A cylindrical shell 1m in diameter and 3m in length has a metal thickness of 10 mm. If it is subjected to an internal pressure of 3 N/mm^2, determine change in length, change in diameter and change in volume. Take E=2x10^5 N/mm^2 and Poisson’s ratio=0.3

Data:

Dia. (d) = 1m = 1000 mm

Length (l) = 3m = 3000 mm

Thickness (t) = 10 mm

Internal pressure (p) = $3 N/mm^2$

$E = 2 \times 10^5 \ N/mm^2$ & $\mu = 0.3$

A] $\delta d = ?$

B] $\delta l = ?$
