← ScienceWhich outcome occurs in lubrication when high shear intensifies?
A)Increased viscous dissipation into heat✓
B)Decreased fluid-film load capacity
C)Cavitation-induced boundary layer adhesion
D)Enhanced elastohydrodynamic regime stability
💡 Explanation
Increased shear rate in lubrication boosts viscous dissipation because internal friction converts energy into heat. Therefore, the oil gets hotter rather than load capacity decreasing; this follows from the definition of viscosity under duress.
