An Analytical Method for Determining Forces within a Triad

The paper presents an original analytical method used in determining the forces within a triad structural group. If the triad is in the mechanical equivalent of the transistor in electronics, representing a very useful structural group, while the transistor is no longer a puzzlement from a long time period, the triad was not too studied analytically, generally being approached by graphic design methods, very elaborated, sometimes very difficult. For this reason, this paper tries to fill a gap in this field. A concrete example of calculation is also presented.
