Shear stress occurs when forces cause a material’s internal layers to slide past each other, like cutting hair with scissors or slicing bread. This force is vital in engineering, preventing failures in bridges and aircraft by calculating a material’s strength under such stress. In biology, blood flow creates shear stress on artery walls, affecting cell […]
