Which outcome relating to lubrication occurs when a journal bearing reaches maximum operating speed?

💡 Explanation

Viscous heating intensifies because shear rate rises with rotational speed, therefore greatly increasing viscous dissipation energy, rather than minimum film increasing or flow decreasing with speed because the increased pumping action.
