The stress-life (S-N) curve for an SAE4340 steel part can be expressed by the equation 10 = 0.0739010 + 3.07395 for the inclined portion. At a particular alternating stress amplitude, the expected life is estimated to be 800,000 cycles. If the expected life is adjusted to 400,000 cycles, what is the ratio of its fatigue stress amplitude to that for 800,000 cycles
