Question 1

If a material is subjected to stress S1in cyclic loading, life of the component is N1cycles and it is N2 &N3 cycles to the corresponding stresses of S2&S3. If the component is subjected to stress S1for n1cycles, stress S2 for n2 cycles and stress S3 for n3 cycles then according to Miner’s rule which of the following statement is true?
