Which outcome occurs in high-speed journal bearings undergoing shear?

A)Fluid film cavitation and bearing damage
B)Increased film thickness prevents contact
C)Reduced viscous heating of lubricant
D)Enhanced load capacity remains constant

💡 Explanation

Fluid film cavitation results when pressure drops during high shear because increased viscous dissipation generates localized boiling (cavitation); therefore, fatigue and bearing damage results, rather than continuous load capacity or reduced viscous effects, which would require different mechanisms or failure modes.
