Tom. .. Was looking for a simpler answer really and maybe there is none
No car parts no running assemblies take a length of rod simple steel say 4 inch long let's say you put tension on it and it elongates and breaks at 10,000 lbs after you establish that,
Let's say at 8,000 lbs there is no permanent elongation call that a max working load ?
Iam sure if you take it repeatedly to 7,999 lbs each time that would be a fatigue cycle
Now in the extreme other direction you put 10 grams of pull on it is that a cycle? I wouldn't think so.
At which point in applying force could you chalk it up as a cycle?
