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 Group Centre created what appeared to a viable structure for a new effort at organising a coup. Bock's dismissal did not weaken Tresckow's position. In fact he soon enticed Bock's successor, General Hans von Kluge, at least part-way to supporting the resistance cause. Tresckow even brought Goerdeler, leader of the civilian resistance, to Army Group Centre to meet Kluge – an extremely dangerous tactic. The entry of the Soviet Union into the war had certain consequences for the civilian resistance. During the period of the Nazi–Soviet Pact, the KPD's only objective inside Germany was to keep itself in existence: it
