A structure, such as a tower/building/column/beam/bridge/machine, is composed of elements that are arranged in a manner to optimally respond to any destructive force applied upon it. Using physical models that expose the effects of gravitational forces shows that the density of the structural elements of a structure should gradually increase from top to bottom in order for the structure to optimally respond to these and other forces.;For optimal response to vibrational forces traveling through a structure/tower/bridge/machine, the structure should be divided in segments that satisfy the Formulas 1, 2, 3, Page 4 of this application. When a structure is divided into segments such that one, or two, or any ratio between these is an Irrational number, the vibration cannot travel through the structure because there isn't a wave length that fits through these different segments.
