Anyone know where they got this fatigue life formula from? It's different than the one I have in Shigley. I've come across 4-5 problems so far where none of the formulas are in MERM. This is starting to scare me.

See section 6-18 of Shigley 8th edition. If it's a different edition, it's the back of the fatigue section for an easy reference so you dont have to dig around the whole chapter.
