"On hot summer days, the tower is up to 30 centimeters higher than on cold winter days"
How much longer can the Eiffel Tower actually endure this? Constantly being stretched out and then shrinking again every year can't be good in the long run.

Loading...1. a) A subway train departs from a stop with an average acceleration of 1.2 m/s2. Calculate how long it takes to reach a speed of 72 km/h. b) The train travels at a constant speed of 72 km/h for 25 seconds. Calculate the distance it covers. c) The train driver has 14 seconds to…
Air is invisible, but could you make it visible by spraying it with paint? And if so, would it still be air?
I'm writing physics on Thursday and need work on efficiency. We started on the topic in the last five minutes of class, and it's still on the test. Does anyone know of any practical exercises that aren't too difficult where I can practice transformers? I haven't found anything good online because the exercises were either…
E.g. with Zip or similar
forever – “drawn” he won’t.
that is not a sustainable burden such as bending it is. Railway rails also make this easy.
This applies to every metal for many buildings.
The tower is not pulled into the length but is simply longer. If this process is mainly homogeneous, no excessive stresses in the metal quickly result in fatigue breaks. So the load is different from how it would really be pulled by an external force.
Don’t worry.
He’s been doing this for 134 years now, and he’ll have a few more centuries.
Would that for this reason extend and shrinkage after 1000 years without maintenance then collapse?
No, he wouldn’t.
Not applicable Rustsbut Peanuts.
And this has also been counteracted since construction by regular renewal of color.
And that’s me too.
What would be the decisive reason why he collapsed? Rusting?
This is only problematic for the paint, because it can get cracks and then rusts the thing.
This is not a big problem, because this overall extension is distributed over the entire height of the Eifel tower.
And for every meter, it’s just a few milimeters, or even less.
That’s not a problem. The heel of man is severely loaded every step and usually lasts a lifetime. The individual parts of the Eiffel Tower change their lengths daily (not only annually). However, they are also regularly maintained and exchanged as needed.
