model equations for the eiffel tower profile

Model equations for the shape of the Eiffel Tower are investigated. Reported here is a third model derived from Eiffel's concern about … A second popular model not connected with Eiffel's writings provides a fair approximation to the tower's skyline profile of 29 contiguous panels. Although the Washington Monument is also wider at its base than at its tip, its shape is not as ideal for a cantilever as is the Eiffel Tower ’s shape. Weidman and Pinelis presented their findings in a paper titled “Model Equations for the Eiffel Tower Profile: Historical Perspective and New Results.” The paper appeared in the July 2004 issue of the journal, “Comptes Rendus Mecanique,” published by Elsevier and the French Academy of Sciences. That shape is exponential. This discrepancy is explained by specific safety factors that Eiffel & Company incorporated in the construction of the lower half of the 300 meter tower. The Tower is used to introduce the cantilever as a structural form because it illustrates the most efficient cantilever form one that is splayed at the support. This model reveals an exponential skyline profile, while the actual tower profile closely resembles two piecewise continuous exponentials. One model purported to be based on Eiffel's writing does not give a tower with the correct curvature. The design and construction of the Eiffel Tower was based, in part, on a uniform horizontal wind model giving 300 kg m − 2 kinematic pressure acting on the surface of the tower. the Eiffel Tower. The first platform's height is 189 feet off the ground, the second's is 380 feet off the ground, and the third platform is 906 feet above ground with the top of the tower reaching 985 feet. The work by Prof. Weidman and Prof. Pinelis, “Model Equations for the Eiffel Tower Profile: Historical Perspective and New Results,” has appeared in the French journal Comptes Rendus Mecanique, published by Elsevier and the French Academy of Sciences. Reported here is a third model derived from Eiffel's concern about wind loads on the tower, as documented in his communication to the French Civil Engineering Society on March 30, 1885. The design and construction of the Eiffel Tower was based, in part, on a uniform horizontal wind model giving 300 kg m−2 kinematic pressure acting on the surface of the tower. paper titled "Model Equations for the Eiffel Tower Profile: Historical Perspective and New Results." The equation for the moment at any point along the Tower uses these two values: For the Eiffel Tower, l = 984 feet and p = 2.6 k/ft; the reaction calculation was made where x = 0 to find M = 1,260,000 ft-k. The result is a nonlinear, integro-differential equation which is solved to yield an exponential tower profile. He found an exact solution of the equation in the form of an exponential function that closely matches the shape of the tower’s upper half. Weidman and Pinelis presented their findings in a paper titled "Model Equations for the Eiffel Tower Profile: Historical Perspective and New Results." Society on March 30, 1885. ” Based on the information, Weidman derived a new equation for the skyline profile – one that “embraces Eiffel’s deep concern for the effects of wind-loading on the tower,” he said. Weidman and Pinelis presented their findings in a paper titled "Model Equations for the Eiffel Tower Profile: Historical Perspective and New Results." The paper appeared in the July 2004 issue of the journal, "Comptes Rendus Mecanique," published The paper appeared in the July 2004 issue of the journal, "Comptes Rendus Mecanique," published by Elsevier and the French Academy of … Eiffel received a patent for his method of construction that eliminates the need for diagonal trellis bars used to resist the moment of an oncoming wind. BASIC EIFFEL TOWER MATH FACTS The height of the Eiffel Tower is around 985 feet.
