A cylindrical cells 3 m long closed at the ends having 1m of internal diameter is subjected to an internal pressure of 1.5 MPa. If the thickness of the shell wall is 15mm. Find the circumferential, longitudinal stress and maximum shear stress. Find the change in diameter, length and volume of the shell. E=2x10^5 N/mm^2 and 1/m=0.3

Data: Cylindrical Shell:

L = 3m = 3000 mm

D = 1m = 1000 mm, $1/m = \mu = 0.3$

$ P = 1.5 \ Mpa = 1.5 \ N/mm^2$ $t = 15 \ mm, E = 2 \times 10^5 \ N/mm^2$
