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.
In physics and mechanics, shear refers to a deformation that causes parallel surfaces to slide past one another (as opposed to compression and tension, which cause parallel surfaces to move towards or away from one another). ...
A subset of the phases of matter, fluids include liquids, gases, plasmas and, to some extent, plastic solids. ...

Dimensions In solid mechanics, shear flow is given in dimensions of force per length. This corresponds to units of newtons per meter in the SI system and pound-force per foot in the English Engineering and British Gravitational systems. Solid mechanics is the branch of physics and mathematics that concern the behavior of solid matter under external actions (e. ...
The newton (symbol: N) is the SI unit of force. ...
The metre, or meter (US), is a measure of length. ...

The pound-force is a non-SI unit of force or weight (properly abbreviated lbf or lbf). The pound-force is equal to a mass of one pound multiplied by the standard acceleration due to gravity on Earth (which is defined as exactly 9. ...
A foot (plural: feet) is a non-SI unit of distance or length, measuring around a third of a metre. ...
Shear flow in semi-monocoque structures The equation for shear flow in a particular web section of the cross-section of a semi-monocoque structure is: 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. ...
 - q - the shear flow through a particular web section of the cross-section
- Vy - the shear force perpendicular to the neutral axis x through the entire cross-section
- Qx - the first moment of area about the neutral axis x for a particular web section of the cross-section
- Ix - the second moment of area about the neutral axis x for the entire cross-section
The second moment of area, also known as the second moment of inertia and the area moment of inertia, is a property of a shape that is used to predict its resistance to bending and deflection. ...
