Which risk increases significantly when hydraulic fluid boils inside actuators?

A)Flow-induced cavitation accelerates erosion
B)Decreased bulk modulus and increased compliance
C)Stiction reduces force transmission ability
D)Increased viscosity increases pumping difficulty

💡 Explanation

When hydraulic fluid boils, vapor replaces liquid. This phase transition reduces the bulk modulus because gas is significantly more compressible than the liquid; therefore compliance increases dramatically, hindering accurate control rather than the other options which occur under different mechanisms or conditions.
