Question

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

A. reduced stress
B. increased stress
C. breaking stress
D. constant stress

Answer 1

Correct Answer - A::C
On crossing the yield region, the material will experience the breaking stress and further elongation causes reduction in stress and break of the wire. So,options a and c are correct.
