← ScienceWhich consequence results when hydrostatic pressure overcomes bearing lubricating oil viscosity?
A)Increased shaft rotational friction✓
B)Decreased heat convection rate
C)Elevated oil cavitation threshold
D)Reduced shaft critical frequency
💡 Explanation
Increased shaft rotational friction occurs because loss of viscous lubrication causes boundary lubrication, therefore friction increases rather than decreasing critical frequency, influenced by mass, rather than lubrication properties.
