When does fatigue occur in metals?

Pick the best soultion for the multiple choices.  Modulus of resilience is: Slope of elastic portion of stress – strain curve Area under the elastic portion of the stress –strain curve Energy absorbed during fracture in a tension test Energy absorbed during fracture in an impact test Slope of the plastic portion of the stress- strain curve                         (   ) Fatigue failure occurs under the condition of: High elastic stress High corrosivity High stress fluctuations High temperature High rate of loading                                                                                     (   )   Creep failure of a material occurs most rapidly when the operating temperature is: Cryogenic temperature Equal to its melting point Grater than 0.4 times its melting point in K Greater than 200 oF Close to boiling point                         (   )   Young’s modulus of a material is indicative of its: Tensile strength Yield Strength Ductility Stiffness Corrosion Resistance…
