For a F1 drive axle the critical resonance frequency is around 2400 rpm. That's why you need to turn it up fast at start over the safe 4000 rpm, and never go down.

Without the ECU you can easily break it by starting too slow

Wouldn’t a multiple of the resonance frequency also be problematic then? Why doesn’t the axle disintegrate at 4800 rpm?
