← TechnologyWhich outcome acutely increases when a hydraulic breaker strikes frozen ground?
A)Accumulator pressure intensifier failure✓
B)Hydraulic fluid thermal expansion
C)Percussive energy transfer efficiency
D)Compressor bypass valve activation
💡 Explanation
Striking frozen ground generates extreme shock, causing pressure spikes exceeding the accumulator's design limits; the intensifier fails because it is attempting to maintain high percussion force. Therefore, accumulator pressure intensifier failure is probable, rather than thermal expansion or compressor bypass.
