← TechnologyWhich risk increases when electrohydraulic actuators experience extremely low hydraulic fluid temperatures?
A)Increased actuator response time✓
B)Decreased actuator efficiency only
C)Reduced actuator stall torque
D)Enhanced fluid laminar flow
💡 Explanation
Increased actuator response time rises because viscosity of the hydraulic fluid drastically increases at lower temperatures; therefore, valve spool movement is sluggish rather than rapid, decreasing responsiveness under time-sensitive control.
