What happens if we have a rotating shaft with high RPM but very little torque?

All else being equal, yes. However Real imbalances will tend to be bigger, or need more labor to bring them down to some fixed value. Power loss due to vibration will tend to be proportional to the ...

Doubt related to S-N curve

Complete reversal is the most basic type of cyclic loading. You can describe it just using the amplitude, because the mean stress is zero. S-N curves obtained in this way can also be used for ...
