I know this may seem a really easy problem but I'm struggling with it and wondered if anyone could tell me where I'm going wrong.
We are given a set of formula.
Stress Ratio R=min/max
Stress Range = бmax -бmin
Stress Amplitude = (бmax - бmin)/2
Mean Stress = (бmax + бmin)/2
Please note that the thing that looks like a 6 is in fact the greek letter for stress.
Then given a table with some of the data missing and some of it filled in.
What I need to know is if I'm given the following information:
R = 0.7 and mean = 85 How do I find the max, min and amplitude?
amplitude = 30 and mean = -50 how do I find max, min and R
Any help would be much appreciated as I'm pulling my hair out over this.
Thanks in advance
