← ScienceWhich outcome results when lubrication undergoes boundary layer breakdown in high-speed bearings?
A)Increased adhesive wear occurs rapidly✓
B)Reduced hydrodynamic pressure stabilizes operation
C)Elastohydrodynamic film thickness increases greatly
D)Lower effective viscosity then prevents damage
💡 Explanation
Increased adhesive wear occurs because asperity contact increases from Stribeck curve effects due to low Reynolds number; therefore, friction increases rapidly, rather than hydrodynamic lubrication protecting surfaces during relative motion.
