a fluid continuously deforms when under the action of shear. This is different to a solid: a solid has a single value of  for each value of  . So the longer a shear stress is applied to a fluid, the more shear strain occurs. However, what is known from experiments is that the rate of shear strain (shear strain per unit time) is related to the shear stress:
