← ScienceWhich outcome occurs when high fluid viscosity impedes lubrication?
A)Increased viscous drag reduces bearing lifespan✓
B)Triboelectric charging causes static discharge
C)Erosion effects sharpen gear teeth faces
D)Alloying elements diffuse from lubricant bath
💡 Explanation
Increased viscosity raises shear stress under motion, exceeding material yield strength because viscous drag transforms kinetic energy by intermolecular friction; therefore higher drag dominates, rather than creating triboelectric effects under ideal loading without viscosity spikes affecting lubrication.
