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
What to the Slave Is the Fourth of July? of their country and their religion and how they rejoice in the name of freedom and liberty and yet they do not offer those things to millions of their country's residents. It is said that America is built on the idea of liberty and freedom, but Douglass tells his audience that more than anything, it is built on inconsistencies that have been overlooked for so long they appear to be truths. According to Douglass, these inconsistencies have made the United States the object of mockery and often contempt. To prove evidence of these inconsistencies, as one historian noted, during the
