In a cylindrical vessel subjected to internal pressure, the longitudinal stress ζL and the circumferential stress, ζn are related by___________________?
Correct answer: A. ζh = 2 ζL
- A. ζh = 2 ζL
- B. ζh = ζL
- C. ζh = ζL/2
- D. No relation exists
Explanation
For a thin-walled cylindrical vessel, force balance on a longitudinal section gives hoop stress equal to twice the longitudinal stress. Therefore, circumferential stress is the critical stress for internal-pressure design.
