What does that mean? Such as the shear force of the pump?
The definition of mechanics of materials is clear: \"Shear\" refers to the relative displacement deformation of a material’s cross-section in the direction of an external force, under the action of a pair of lateral forces that are (1) close to each other, (2) of equal magnitude, and (3) directed in opposite directions (i.e., forces perpendicular to the surface on which they act). The force that can cause shear deformation in a material is called shear force. The cross-section that undergoes shear deformation is called the shear plane. The key to determining whether there has been “shearing” is whether there is relative displacement in the cross-section of the material.
Could you explain it in simpler terms? For example, let’s take a case
Put simply, it’s like chopping vegetables :) The shear force of a pump refers mainly to the shear exerted by the impeller on the water
For the human body. It refers to the friction between blood flow and the vascular endothelium, and is another cause of pressure ulcers. Pathological studies have confirmed that atherosclerotic lesions occur in areas with low shear stress. Animal experiments have shown that high shear stress can prevent the development of atherosclerotic lesions. Additionally, the hemodynamic shear stress refers to the force exerted by blood flow on the unit area of the blood vessel wall, also known as shear force. Actually, they’re all the same; it depends on how you view it
