Three identical fatigue specimens (denoted a, b, and c) are fabricated from a nonferrous alloy. each is subjected to one of the maximum-minimum stress cycles listed below; the frequency is the same for all three tests.
specimen σmax (mpa) σmin (mpa)
a 460 -360
b 410 -310
c 350 -350
rank the fatigue lifetimes of these three specimens from the longest to the shortest.
