Which outcome occurs when hydraulic fluid warms excessively?

A)Reduced system response time
B)Increased component structural strength
C)Pressure relief valve setpoint increase
D)Improved pump cavitation performance

💡 Explanation

Warming decreases a hydraulic fluid’s viscosity; this *viscosity reduction* lowers friction and resistance to flow. Because response time depends on reaching actuator pressure, the decreased viscosity reduces the system response; therefore the system becomes more spongy, because loss of energy occurs rather than transmitting pressure effectively.
