: Always acts parallel to the plane of the cross-section.
Shear stress is a fundamental concept in engineering and physics that describes how materials respond to forces acting parallel to their surfaces. Unlike normal stress, which pushes or pulls directly against a surface, shear stress causes layers of material to slide against one another. Download Shear Stress Exercise pptx
: Shear stress is often confused with shear force; however, stress represents the force intensity per unit of area. Common Types of Shear Stress : Always acts parallel to the plane of the cross-section
