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
Memorial to the German Resistance there was never an effective resistance movement. Particular attention is given to military resistance figures such as Claus von Stauffenberg, Ludwig Beck, Erwin von Witzleben, Günther von Kluge, Erich Hoepner, Hans Oster and Friedrich Olbricht. This underlines the modern German military doctrine, which holds that military officers have a moral duty which goes beyond the blind obedience of orders, and that those officers who plotted to kill Hitler were not traitors but heroes. The same point is made about other Germans who went into exile and assisted the Allied war effort against Germany, such as Marlene Dietrich. The museum also
