Which risk increases significantly when excessively reducing turbocharger impeller shaft diameter?

💡 Explanation

Reduced diameter raises stress concentration; therefore high-cycle fatigue becomes much more likely due to increased cyclic strain from turbine operation. This is because **stress concentration** causes premature failure rather than immediate surge or cavitation, occurring under design limits.
