Q. What is the effect of plating on the fatigue strength of a machine element?(Marks: 02)- Published on 19 Oct 15a. plating increases fatigue strength of a machine element
b. plating decreases fatigue strength of a machine element
c. plating does not affect fatigue strength of a machine element
d. unpredictable
ANSWER: plating decreases fatigue strength of a machine element
The internal residual stresses importantly affect the fatigue strength of a machine element. These internal residual stresses are affected by plating. Thus plating decreases fatigue strength of a machine element.
