← TechnologyWhich actuator issue results when hydraulic fluid viscosity increases significantly during rapid cycling?
A)Reduced control responsiveness✓
B)Increased positional accuracy
C)Higher energy transmission
D)Enhanced self-lubrication
💡 Explanation
Stiffening occurs because increased viscosity raises the hydraulic resistance, limiting fluid flow; therefore, actuator speed decreases, which limits motion precision, rather than improving lubricant effects or energy transfer under time constraints.
