  • [In order to express the dependence of the tension at the interface of two bodies in terms of the forces exercised by the bodies upon themselves and upon one another, we cannot do better than follow the method of Dupre.
  • If T12 denote the interfacial tension, the energy corresponding to unit of area of the interface b Q FIG.
  • A comparison with another method of generating the interface, similar to that previously employed when but one body was in question, will now allow us to evaluate T12.
