Suicides

Surprised nothing is written about suicides at the Tower. "Sad fact: The Eiffel Tower is the most popular landmark for suicides in France. In an average year, four people commit suicide by jumping off the tower or, occasionally, by hanging themselves from its wrought iron beams." http://www.neatorama.com/2007/07/16/the-eiffel-tower-story/ —Preceding unsigned comment added by 173.172.19.51 (talk) 05:42, 12 May 2011 (UTC)

Source

seems like someone just threw this in. No source personally i find it hard to believe unless it was spider man XD 'A Frenchman scaled the tower during the German occupation to hang the French flag.'

Replica

the Tokyo Tower is more or less a replica; mention in article ?

Wind considerations: explanations of what?

In the section titled "Wind considerations" is the following sentence:

"Several explanations have been proposed over the years; the most recent is a nonlinear integral equation based on counterbalancing the wind pressure on any point on the tower with the tension between the construction elements at that point."

All right. But there is nothing preceding this to tell us what question this is intended to explain. (Possibly some later edit inadvertently orphaned the last half of a paragraph?) I could remove it, but I would prefer that someone alter the paragraph so that it makes sense.

Any takers?

• May I suggest the rewriting of that section, preferably by "un ingénieur" (!) ?
• Also reading of this fr:wiki article "Histoire de la Tour Eiffel"[1].

Ormewood is correct that later revisions by someone (to put all wind considerations into one section) caused a loss of continuity. I was the original author of the section "Shape of The Tower" in March of 2007, so I know that the orphaned sentences answer the question: What mathmatical calculation was Eiffel referring to? I tried to edit the article, but found it is now semi-protected owing to excessive vandalism. I propose that an autoconfirmed user revise the entire paragraph as follows:

In search of what mathmatical calculation Eiffel referred to, researchers have found that Eiffel used empirical and graphical methods accounting for the effects of wind rather than a specific mathmatical formula. Careful examination of the tower shows a basically exponential shape; actually two different exponentials, the lower section overdesigned to ensure resistance to wind forces. Several mathmatical explanations have been proposed over the years; the most recent is described as a nonlinear integral equation based on counterbalancing the wind pressure on any point on the tower with the tension between the construction elements at that point. As a demonstration of the tower's effectiveness in wind resistance, it sways only 6–7 cm (2–3 in) in the wind.

I would be happy for any assistance in further editing or rewriting.--Tvbanfield (talk) 17:19, 15 January 2011 (UTC)

I made the change suggested above by Tvbanfield, with a few changes intended to clarify the meaning. I may edit it a bit further to improve the readability of the paragraph. Hope this is agreeable to all...Ormewood (talk) 21:42, 15 January 2011 (UTC)

Maybe I should clarify a bit...it seemed to me that when "several mathematical explanations have been proposed over the years", that these explanations were not suggestions of what calculations Eiffel used. As pointed out, he used empirical and graphical methods, not a specific formula...so the formula proposed recently would be one that explained the success of the design of the tower in dealing with the forces of the wind on it rather than an explanation of which methods Eiffel used. I changed the paragraph to reflect this.Ormewood (talk) 21:52, 15 January 2011 (UTC)

Ormewood's modifications are fine by me. I think that the recently developed mathmatical explanations were simply the result of an academic objective of finding a formula that would explain the design based on the principles described by Eiffel.

Now I find that reference (3) is no longer valid and that the maximum amplitude of wind sway at the top of the tower was measured in 1999 to be 9 cm. Current reference would be:http://www.tour-eiffel.com/component/content/article/7-faq/115-histoire-technique --Tvbanfield (talk) 21:33, 2 April 2011 (UTC)

It seems to me that the image shown on the right side of the "wind considerations" section is actually the fourth floor (the top floor), not the third floor, as the caption of the picture states. If counting american style, that is even floor number five. I could not correct the page, even after login into wikipedia. I don't know why. Is the page locked in some way? — Preceding unsigned comment added by Csoler (talk • contribs) 18:58, 6 June 2011 (UTC)

File:Tour Eiffel Wikimedia Commons.jpg to appear as POTD soon

Hello! This is a note to let the editors of this article know that File:Tour Eiffel Wikimedia Commons.jpg will be appearing as picture of the day on March 31, 2011. You can view and edit the POTD blurb at Template:POTD/2011-03-31. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks! howcheng {chat} 17:22, 28 March 2011 (UTC)

Picture of the day

The Eiffel Tower as seen from the Champ de Mars. At 324 metres (1,063 ft) tall, the tower, an iron lattice tower, is the tallest building in Paris, the most-visited paid monument in the world, as well as one of the most recognizable structures in the world. Named after its designer, Gustave Eiffel, it was built as an entrance arch for the 1889 Exposition Universelle and has since become the most prominent symbol of both Paris and France.Photo: Benh Lieu Song

Height

The new height of the eiffel tower is 327 meters now because a new antenna is installed. But this page is protected so I can't modify. —Preceding unsigned comment added by 90.3.132.161 (talk) 21:33, 14 April 2011 (UTC)

No one else should modify the page either because you have forgotten that all important citation for your claim. 86.176.152.238 (talk) 11:25, 20 June 2011 (UTC)

Restaurants

Restaurants

The tower has two restaurants: "Altitude 95", on the first floor "311 ft (95 m)" above sea level;

I just visited the Eiffel Tower and the restaurant on the first floor was call "58 Tour Eiffel". The first level of the Eiffel Tower is 57m to 58m. A visual inspection of a photo of the tower will show that the first level is not approximately 1/3 of the overall height, i.e. 95m/324m. I reference p. 17 of the travel guide DK "Eyewitness Travel Top 10 Paris" ISSN 1479-344X which lists the information correctly. — Preceding unsigned comment added by Ndigiovanni (talk • contribs) 20:34, 24 June 2011 (UTC)

Bolted Together?

I visited the Eiffel Tower some years ago and recall that it was bolted together, not riveted. Anybody got any RS on this? Also, the color is beige, which looks black from a distance. Anybody know why beige was chosen as the color? Has the color of the tower ever been a different color? 64.169.154.63 (talk) 09:04, 30 June 2011 (UTC)
