1.	What is fatigue stress?(a) The stress endured by an observer(b) Stress divided by strain and multiplied by conductivity(c) The amount of stress, a material can tolerate repeatedly without failure(d) The stress endured perpendicular to the observerThe question was asked during an online interview.This key question is from Aircraft Materials in section Testing Aircraft Materials of Aerospace Materials & Processes
Answer» Correct option is (c) The amount of stress, a material can TOLERATE REPEATEDLY without failure Easy explanation: The fatigue stress of a material is the stress it can tolerate several TIMES, without resulting in any failure. Each material has that fatigue stress and if it is CROSSED it is unsafe to load the material FREQUENTLY.
