A long cylinder pressure vessel with closed ends has an internal pressure of 3 MPa. Calculate the hoop stress, sigma (theta) and the longitudinal stress, sigma (z) for the vessel if the internal diameter is 25 cm.use the following three wall thickness: 1,4,8 cm

A) calculate the stresses using the thin wall assumption, and the internal diameter.

B) calculate the stresses using the thin wall assumption and the mean diameter.

C) calculate the stresses sigma (r) and sigma (theta) using the thick wall assumptions. determine the maximum values for sigma (r) and sigma (theta).

D) calculate the percentage error of sigma (theta) a) from C)
