Cylindrical shear stress

Wall shear stress expresses the retarding force (per unit area) from a wall in the layers of a fluid flowing next to the wall. It is defined as: Where is the dynamic viscosity, the flow velocity and the distance from the wall. It is used, for example, in the description of arterial blood flow in which case which there is evidence that it affects the atherogenic process. WebUnlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section. To keep things simple, we're going to focus on structures with a circular cross section, often …
