On gradual loading , stress - strain relationship for a metal wire is as follows . Within proportionality limit , stress prop strain or, `"Stress"/"strain"` = a constant for the material of wire.
Just on crossing the yield region, the material will have

Options

A. increased and breaking stress
B. reduced and breaking stress
C. constant stress
D. None of these

Answer

B

Explanation

On crossing the yield region, the material will experience the breaking stress and further elongation causes reduction in stress and breaking of the wire.
