Therefore, the analysis will This was Eiffel's point more than a century ago, when he wrote about the four stout legs supporting the legendary tower: "Before they meet at such an impressive height, the uprights appear to spring out of the ground, moulded in a way by the action of the wind itself.". distinction can be made mathematically by the following relation: MPSetEqnAttrs('eq0001','',3,[[124,44,19,-1,-1],[165,58,25,-1,-1],[208,72,32,-1,-1],[186,65,29,-1,-1],[249,87,38,-1,-1],[311,109,48,-2,-2],[518,182,81,-3,-3]]) Given that, it is easy to infer that the axis of symmetry runs straight down a point onthex-axis. Weidman, who said he became obsessed with the problem, began to read more about the life of Eiffel and his construction efforts. File history. 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. Instead, Eiffel's engineers used graphical results to calculate the strength needed to support its tremendous weight, as well as empirical evidence to account for the effects of wind. The tower was designed to be the centerpiece of the World's Exposition in Paris, marking the centennial of the French Revolution. The Eiffel Tower was built and designed this way so it could support the wind and so it would be more . Plotting the actual shape of the tower reveals two separate exponential sections that are hooked together, he said. The paper appeared in the July 2004 issue of the journal, "Comptes Rendus Mecanique," published by Elsevier and the French Academy of Sciences.
