Assertion (A): Normal stress of one nature (compressive or tensile) acting along one of the three orthogonal axes of a member will produce strains of the same nature in its direction and strains of opposite nature along with the other two directions.
Reason (R): Sum of the strains along the three orthogonal axes equals volumetric strains.
Of these statements:
1
Both A and R are true and R is the correct explanation of A
2
Both A and R are true but R is not the correct explanation of A
3
A is true but R is false
4
A is false but R is true
