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 to whom he was outwardly subservient, of what he knew. This was a striking example of the code of silent solidarity among senior German Army officers, which was to survive and provide a shield for the resistance groups down to, and in many cases beyond, the crisis of July 1944. On 13 September, the British Prime Minister, Neville Chamberlain, announced that he would visit Germany to meet Hitler and defuse the crisis over Czechoslovakia. This threw the conspirators into uncertainty. When, on 20 September, it appeared that the negotiations had broken down and that Chamberlain would resist Hitler's demands, the
