Define Threshold stress regarding stress-corrosion cracking.

Define Threshold stress regarding stress-corrosion cracking. Correct Answer The minimum stress required to prevent cracking

Increasing stress decreases the time before cracking occurs. Threshold stress is the minimum stress required to prevent cracking. It depends on temperature, alloy composition, and environment composition.

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R) Assertion (A): In Gunn effect, when electric field is varied from zero to a threshold value the drift velocity decreases. Reason (R): Beyond the threshold electric field, if the electric field is increased, the drift velocity is decreased and the diode exhibits negative resistance. In the light of the above statement, choose the most appropriate answer from the options given below:
