Shear flow themselves. In a shearing flow, adjacent layers of fluid move parallel to each other with different speeds. Viscous fluids resist this shearing motion. For a Newtonian fluid, the stress exerted by the fluid in resistance to the shear is proportional to the strain rate or shear rate. A simple example of a shear flow is Couette flow, in which a fluid is trapped between two large parallel plates, and one plate is moved with some relative velocity to the other. Here, the strain rate is simply the relative velocity divided by the distance between the plates. Shear flows in fluids
The Resistance to Theory about language." The resistance to theory is therefore, according to de Man, a resistance to reading: "Nothing can overcome the resistance to theory since theory 'is' itself this resistance." De Man concludes however by stating that "literary theory is not in danger of going under; it cannot help but flourish, and the more it is resisted, the more it flourishes, since the language it speaks is the language of self resistance." (p. 365) The Resistance to Theory "The Resistance to Theory" is an essay by Paul de Man (1919–83), a renowned literary critic and theorist belonging to the Yale School
