Understanding Allowance Stress in Vessels

[lilMissMindset]

HI. :)

help me please.

when the problems says that there is an allowance stress, especially in thin or thick walled vessels, what kind of stress could it be?

thanks!

If the type of allowable stress is not specified (e.g., allowable tensile stress, or allowable shear stress), assume that the allowable stress is a general upper limit. If that doesn't feel right, seek clarification from the instructor.
