Simple Stress and Strain-II

Assertion A: ...

Question

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 the other two directions.
Reason (R): Sum of the strains along the three orthogonal axes equals volumetric strain.
