Longitudinal stress induced in a thin walled cylindrical storage vessel is __________________?
Correct answer: B. pD/4t
- A. pD/2t
- B. pD/4t
- C. pD/3t
- D. pD/6t
Explanation
For a thin cylindrical vessel, pressure produces a longitudinal stress of pD/(4t), while the circumferential stress is twice as large, pD/(2t). Hence the longitudinal expression is pD/4t.
