← ScienceWhich effect occurs when lubricant viscosity decreases in journal bearings?
A)Increased asperity contact and friction✓
B)Improved hydrodynamic load support
C)Enhanced damping of shaft vibrations
D)Reduced oil film temperature gradient
💡 Explanation
Decreased viscosity leads to thinner oil films, weakening hydrodynamic lubrication. Hydrodynamic lubrication relies on Viscous Flow; therefore, increased asperity contact occurs because the oil film can no longer effectively separate surfaces, rather than maintaining separation with proper lubricant thickness.
