I ask ChatGPT: How do you calculate the fatigue life of a steel coil spring knowing the ultimate strength of the material, the maximum and minimum stress the spring will see, and the slope of the SN curve? It comes up with an explanation which makes sense up until the final calculation. It shows an equation for Number of Cycles to Failure (Nf) to be equal to .97 but then it says this is approximately 14,000 cycles. See attached .jpg. I've asked ChatGPT about this math and got no satisfactory explanation. I need to know how this math shows that Nf is 14,000 cycles so I can duplicate the math. I've tried other versions of the question, and it comes down to Nf = small number, but then ChatGPT says it is approximately a much larger number.
