I have some calculations I would like to make, though I am having trouble finding information. I have a circular hollow shaft made of steel. I would like to calculate the breaking point of said shaft at 1000 cycles and 1000000 cycles. What kind of information/properties of the metal needs to be known. Is there a formula for this kind of calculation, or is this something that may come from a table of data after performing fatigue tests. I am kind of new to this, sorry if my questions are a little vague.(adsbygoogle = window.adsbygoogle || []).push({});
