Page:Essay on the theory of capillary phenomena. Theory of surface adhesion of liquid (1879).pdf/7

 not only differ significantly from each other in their counterparts, but even, in the interpretation of some authors, they become directly hostile to each other. In this I decide to offer my readers a special point of view on the theory of surface adhesion of liquid. This view is capable, it seems to me, of reconciling both of the abovementioned directions, and also of removing from Young’s theory the most important accusation that its opponents bring to it, claiming that it does not have a sufficient basis in general principles of rational mechanics. A theoretical consideration of those questions that lead to the idea of ​​partial forces will significantly is facilitated through the introduction of the auxiliary concept of pressure. Kowu further defined as the resultant force of a certain system of partial interactions and showed that the influence of these interactions on the equilibrium of particles of any body can be determined as long as it is known further at every point inside the body. After that the concept of pressure was usefully used in the study of the equilibrium and movement of certain physical bodies, what are the solid ynpyria of the body, liquids undergoing destruction inside, etc. Applying this concept to the consideration of capillary phenomena leads to the theory of surface adhesion in the general principles of mechanics, including the elimination its disagreement with Laplace's theory.

I considered it appropriate to preface this theory with a review of those general theorems about pressure that Kowu found and were accepted by many authors and included in some educational courses.
