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
German resistance to Nazism German resistance to Nazism German resistance to Nazism (German: "Widerstand gegen den Nationalsozialismus") was the opposition by individuals and groups in Germany to the National Socialist regime between 1933 and 1945. Some of these engaged in active resistance with plans to remove Adolf Hitler from power by assassination and overthrow his regime. The term "German resistance" should not be understood as meaning that there was a united resistance movement in Germany at any time during the Nazi period, analogous to the more coordinated Polish Underground State, Greek Resistance, Yugoslav Partisans, French Resistance, Dutch Resistance, Norwegian resistance movement and Italian Resistance.
