The contact between a cylindrical flat indenter and an incompressible, nonviscous liquid is considered. The behaviour is totally controlled by the assumed constant surface tension and gravity. An analytical approach and a numerical solution are developed to describe the shape of the surface as a function of the applied force. In the absence of an exact solution, an approximate solution is proposed.
