It's located in Paris on the Champ de Mars. Suggest Corrections. Calculations by Pinelis showed that all existing solutions to Chouard's equation must be either parabola-like -- which the Eiffel Tower is not -- or "explode to infinity" at the top of the tower. This more curved shape was selected because it was the most efficient in But such a tower, never having been successfully erected, raised a chronic concern of Eiffel that he expressed frequently in his communications. into two of double thickness. This Why is the parabola considered such a strong shape? (This is a root of the quadratic equation describing a parabola resting against the right side of the Tower, so the curve of the Tower's right side is described by the negative arm of the parabola.)
