Which outcome occurs when a hydraulic actuator in a high-speed robotic arm experiences internal obstructions?

💡 Explanation

Accelerated pitting occurs when obstructions increase local fluid velocities, decreasing pressure. Because pressure drops below the fluid's vapor pressure, cavitation bubbles form and collapse violently, leading to erosion, therefore pitting occurs rather than enhanced accuracy.
