← ScienceWhich outcome increases when an ultracentrifuge encounters asymmetric isotopic distribution?
A)Resonance frequency widens significantly
B)Drive shaft fatigue escalates severely✓
C)Magnetic damping stabilizes rotor speed
D)Containment vessel pressure diffuses evenly
💡 Explanation
Increased asymmetrical isotopic distribution causes imbalanced Coriolis forces during high-speed operation, leading to increased cyclic stress via resonant vibrations, therefore fatigue life decreases drastically, rather than resonance widening or pressure even distribution, because these are distinct issues related to instrument precision, temperature and operation.
