shear force

American  

[sheer fawrs] / ˈʃɪər ˈfɔrs /

noun

1. Civil Engineering. a force that acts parallel or tangential to a structural surface, causing it to deform in opposite directions, an example of which is a knife cutting through a box, which separates and pushes the surface apart.

shear force Scientific  

1. A force acting in a direction parallel to a surface or to a planar cross section of a body, as for example the pressure of air along the front of an airplane wing. Shear forces often result in shear strain. Resistance to such forces in a fluid is linked to its viscosity.

2. Also called shearing force

Example Sentences

However, when the capsules are collapsed, the suspension transforms into a non-Newtonian fluid, meaning that its viscosity will change in response to shear force -- the greater the shear force, the more fluid it becomes.

Scientifically, a Newtonian fluid is one in which the shear force varies in direct proportion with the stress it puts on the material, known as the shearing strain.

The pole in Figure 5.24 is at a 90.0º bend in a power line and is therefore subjected to more shear force than poles in straight parts of the line.

In the situation shown in Figure 15.2b, a 13% increase in the shear force could easily be enough to tip the balance between shear force and shear strength.
