← ScienceWhich outcome will occur when a hydraulic damper's viscosity decreases due to elevated temperature?
A)Increased damping force at startup
B)Reduced settling time after impulse✓
C)Elevated energy absorption during compression
D)Increased seal leakage under load
💡 Explanation
Decreased viscosity leads to a lower damping coefficient. Specifically, *fluid shear* reduces resistance; therefore settling time reduces, rather than force increasing, because decreased viscosity allows faster piston movement; the pressure drop decreases, and seals may be unaffected.
