Which risk increases when a hydraulic actuator regulating turbine blade pitch experiences excessively rapid cycling?

💡 Explanation

Increased thermal fatigue cracking becomes a risk because rapid cycling causes **cyclic stress**, leading to localized heating and expansion; therefore cracks propagate, rather than uniform expansion, because stress concentrates at imperfections.
