Shear stress is a stress state where the stress is parallel or tangential to a face of the material, as opposed to normal stress when the stress is perpendicular to the face. The variable used to denote shear stress is τ (tau). Stress is the internal distribution of force per unit area that balances and reacts to external loads applied to a body. ...

The formula for shear stress in a beam is: With V being the shear force at that location, Q being the first moment of area, t being the thickness in the material perpendicular to the shear and I being the second moment of area of the cross section. The first moment of area, also known as the first moment of inertia, is usually denoted by the symbol Q and is a property of a shape that is used to predict its resistance to shear stress. ...
The second moment of area, also known as the area moment of inertia and less precisely as the moment of inertia, is a property of a shape that is used to predict its resistance to bending and deflection. ...
Structural members in pure shear stress are the torsion bars and the driveshafts in automobiles. Riveted and bolted joints may also be mainly subjected to shear stress. Cantilevers, beams, consoles and column heads are subject to composite loading, consisting of shear, tensile and compressive stress. A torsion spring is a ribbon, bar, or coil that reacts against twisting motion. ...

Shear stresses within a semimonocoque structure may be calculated by idealizing the crosssection of the structure into a set of stringers (carrying only axial loads) and webs (carrying only shear flows). Dividing the shear flow by the thickness of a given portion of the semimonocoque structure yields the shear stress. Thus, the maximum shear stress will occur either in the web of maximum shear flow or minimum thickness. Monocoque (French for single shell) or unibody is a construction technique that uses the external skin of an object to support some or most of the load on the structure. ...
Shear flow is: in a solid body, the gradient of a shear force through the body; in a fluid, it is the flow induced by such a force gradient  see Viscosity for a fuller treatment. ...
Also constructions in soil can fail due to shear; e.g., the weight of an earthfilled dam or dike may cause the subsoil to collapse, like a small landslide. Download high resolution version (948x622, 131 KB)A section of the A6187, near Castleton, UK, destroyed by geological subsidence. ...

Shear stress is relevant to the motion of fluids upon surfaces, which result in the generation of shear stress. Particularly, the laminar fluid flow over the surface has a zero velocity and shear stress occurs between the zerovelocity surface and the highervelocity flow away from the surface. laminar and turbulent water flow over the hull of a submarine In fluid dynamics, laminar flow is a flow regime characterized by high momentum diffusion, low momentum convection, and pressure and velocity independence from time. ...
