Which outcome results when lubricated gears operate below specified viscosity?

A)Increased adhesive gear tooth wear
B)Enhanced hydrodynamic film formation
C)Decreased operating temperature stability
D)Reduced lubricant oxidation potential

💡 Explanation

Increased adhesive wear occurs due to boundary lubrication regime because diminished viscosity thins the lubricant film, allowing metallic contact between gears. Therefore adhesive wear rises, rather than hydrodynamic lubrication, because the fluid film collapses under load conditions.
