Question

The Striheck curve, represents the relationship between film thickness and elastic deformation; shows that friction coefficient decreases as viscosity of the lubricant increases; represents the relationship between torque, viscosity and surface roughness; shows that the friction coefficient is independent of load applied; illustrates how the coefficient of friction varies with changing sliding speed and load the presence of a viscous lubricant. The viscosity of a lubricant, is defined by the ratio of film thickness to shear rate; is determined by its ability to reduce surface damage; is equivalent to the fluid's density; is one of the factors necessary in developing a hydrodynamic oil film; is governed both by its physical and chemical properties.

Explanation / Answer

option 5..Stribeck curve is basically a curve between coefficient of friction and bearing number. Bearing number can be defined as sliding velocity, relative sliding velocity lubricant with viscosity per unit load.

option 4
