← ScienceWhich outcome occurs when lubricating oil within a journal bearing exceeds thresholds?
A)Increased asperity contact and friction✓
B)Enhanced hydrodynamic film thermal conduction
C)Cavitation number decreases proportionally
D)Reduced viscosity increases squeeze film damping
💡 Explanation
Increased temperature reduces viscosity, leading to lubricant breakdown. Because of the lower viscosity causes allows increased asperity contact and friction due to less effective hydrodynamic lubrication; therefore, friction increases rather than decreased damping or thermal conduction under threshold conditions.
