Which risk increases when a hydraulic actuator controlling a large marine rudder experiences rapid, repeated adjustments?

💡 Explanation

Rapid, repeated adjustments cause frequent opening/closing of the bypass valve for flow regulation; this generates significant frictional heat in the narrowly constricted flow path undergoing throttling. Therefore, thermal overload intensifies because the bypass valve's dissipation capacity is being challenged, rather than alternative effects on pump efficiency.
