What is the primary difference between "shear stress" and "shear rate"?

Shear stress is a function of time, while shear rate is constant

Shear stress refers to the force applied to a fluid, and shear rate refers to the rate of deformation

Shear stress affects only solids, while shear rate affects only liquids

Shear rate is independent of force, while shear stress is dependent on force
