What is viscous resistance of journal bearing?

Let us consider that a shaft is rotating in a journal bearing and think that oil is used as a lubricant in order to fill the clearance between the shaft and journal bearing. Therefore oil will offer viscous resistance to the rotating shaft.

What is the relation between viscosity and shear stress?

Shear rate is the velocity of the moving plate divided by the distance between the plates. According to Newton's Law, shear stress is viscosity times shear rate. Therefore, the viscosity is shear stress divided by shear rate.
