the shear stresssapplied for various non-Newtonian liquids. Curve (1) can represent

a slightly aggregating dispersion of very small particles, (2) a solution of polymers

that interact with each other to give a weak gel and hence produce a yield stress (of

about 0.03 Pa), and (3) a nongelling polymer solution.
