The longitudinal stress induced in a thin walled cylindrical vessel under internal pressure is_________________?
Correct answer: B. pd/4t
- A. pd/2t
- B. pd/4t
- C. pd/t
- D. pd/8t
Explanation
For a thin cylindrical vessel, the longitudinal stress is obtained by balancing pressure force on a longitudinal section with the wall resisting force, giving σL = pD/(4t). The hoop stress is twice this value, pD/(2t).
