what is the fatigue ratio? if the tensile strength sts of an alloy is 900 mpa, what, roughly, would you expect its endurance limit se to be?

The Endurance limit or Fatigue limit of a metal alloy is 360 mpa.What is Fatigue Ratio?The ratio between tensile strength and fatigue strength or fatigue limit Numerous materials can have their fatigue qualities estimated using data from tension testing using the fatigue ratio.What is the Fatigue limit?The stress level below which an unlimited number of loading cycles can be given to a material without inducing fatigue failure is known as the fatigue limit or endurance limit.Given:Tensile strength of an alloy = 900mpaThe ratio of minimum to maximal fatigue stress is called fatigue stress or R,     [tex]R=\frac{σmin}{σmax }[/tex]. There are a certain number of load cycles per second or stress frequency f. With each stress parameter, a material's vulnerability to fatigue damage and failure grows.Therefore, the endurance limit is 360 mpa.To learn more about the Endurance Limit from the given linkhttps://brainly.com/question/15282669#SPJ4
