How to calculate q in shear stress
WebShear stress is a mechanical force that occurs when blood flows through the blood vessels and exerts frictional forces on the endothelial cells lining the vessels. This mechanical force is known to play an essential role in regulating vascular function, including blood flow and blood pressure, by inducing the release of nitric oxide (NO) from endothelial cells. WebNormal Stress: Stress acts perpendicular to the surface (cross section). Second Moment of Area: The capacity of a cross-section to resist bending. Shear Stress: A form of a stress acts parallel to the surface (cross section) which has a cutting nature. Stress: Average force per unit area which results strain of material. Supplements:
