Shear Stress

+**Shear Stress**

+Shear stress is a force acting parallel to a surface, causing one part of a material to slide past another. This internal resistance, often critical in the study of [Fluids](/wiki/fluid) and [Deformation](/wiki/deformation), resists the sliding motion without changing volume. It is a fundamental concept in material science and engineering.
