Introduction:

The walls of the cylinder will have a longitudinal stress as well as a circumferential stress.

 

Description:

Consider now again the same figure and the vessel could be considered to have closed ends and contains a fluid under a gage pressure p.Then the walls of the cylinder will have a longitudinal stress as well as a ciccumferential stress.

Total force on the end of the cylinder owing to internal pressure


= pressure x area


= p x π d2 /4


Area of metal resisting this force = πd.t. (approximately)


because πd is the circumference and this is multiplied by the wall thickness
