Assertion (A): A thin cylindrical shell is subjected to internal fluid pressure that induces a 2 – D stress state in the material along the longitudinal and circumferential directions
Reason (R): The circumferential stress in the thin cylindrical shell is two times the magnitude of longitudinal stress.
a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true but R is NOT the correct
(c) A is true but R is false
(d) A is false but R is true
