Which limitation leads to actuator stall in high-speed hydraulic robotic arms?

💡 Explanation

Actuator stall can occur due to pressure intensification via Bernoulli’s equation because fluid velocity increases rapidly within tight valve clearances generating extreme pressure spikes sufficient to overcome actuator holding capacity; therefore precise spool valve design is required rather than using less-precise manufacturing tolerances alone.
