Mercury exhibits more cohesion than adhesion with glass Rain water flux from a canopy. Among the forces that govern drop formation: cohesion, surface tension, Van der Waals force, Plateau–Rayleigh instability. Water, for example, is strongly cohesive as each molecule may make four hydrogen bonds to other water molecules in a tetrahedral ...
As the adhesive solidifies, its internal strength, the cohesion, increases. The cohesion is also based on physical interactions, in this case between the adhesive polymers. In the case of adhesives which cure by a chemical reaction, i.e. the formation of polymers by a chemical reaction of the adhesive constituents, the resulting chemical bonds ...
Gibbs emphasized that for solids, the surface free energy may be completely different from surface stress (what he called surface tension): [13]: 315 the surface free energy is the work required to form the surface, while surface stress is the work required to stretch the surface. In the case of a two-fluid interface, there is no distinction ...
A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion. More narrowly, binders are liquid or dough-like substances that harden by a chemical or physical process and bind fibres, filler powder and other particles added into it.
Expressions in terms of cohesion and friction angle [ edit ] Since the Drucker–Prager yield surface is a smooth version of the Mohr–Coulomb yield surface , it is often expressed in terms of the cohesion ( c {\displaystyle c} ) and the angle of internal friction ( ϕ {\displaystyle \phi } ) that are used to describe the Mohr–Coulomb yield ...

As the talk page says, the article, or rather paragraph, is copied and pasted from somewhere else. I was looking for information on chromatography and since cohesion is a very big part of the topic, I would have definitely though that the article would have more information on the relationship between cohesion and chromatography.
For two-dimensional, plane strain problems the strain-displacement relations are = ; = [+] ; = Repeated differentiation of these relations, in order to remove the displacements and , gives us the two-dimensional compatibility condition for strains
