Which risk increases in hydraulic systems that use accumulators when system pressure exceeds the accumulator's design limit?

💡 Explanation

When system pressure exceeds design limits, over-pressurization of the accumulator occurs because the gas or bladder material is stressed beyond its yield point, leading to structural failure. Therefore rupture is the risk, rather than vapor lock, oil oxidation, or spool sticking, which arise from thermal or contamination issues.
