Why Eiffel Tower Gets Taller By 6 Inches?

Why Eiffel Tower Gets Taller By 6 Inches?

The height of the Eiffel Tower is 324 meters on average-changes looking on the season.

The Eiffel Tower gets taller by up to six inches during the summer when the temperature reaches as high as 40°C.  Extreme heat causes the metal at the bottom to expand, increasing the peak of the Eiffel Tower. It also causes the top of the tower to tilt far away from the sun by up to 7 inches. That’s because Steel expands in hot and contracts in cold. So, The Eiffel Tower is six inches taller in summer than winter.

When the recent summer sun beats down on that, thermal expansion causes the metal to grow. The tower can swell tall by the maximum amount as 15 centimeters (6 inches). But once the recent sun goes down, the expansion decreases.

Construction of the Eiffel Tower

When construction of the tower began on the Champs de Mars, a group of 300 artists, sculptors, writers and designers sent a petition to the commissioner of the Paris Exposition, pleading him to halt construction of the "ridiculous tower" that might dominate Paris like a "gigantic black smokestack."
But the protests of Paris' artistic community fell on deaf ears. Construction of the tower was completed in only over two years, on March 31, 1889.

Each of the 18,000 items used to build the tower was calculated specifically for the project and ready in Eiffel's mill on the outskirts of Paris. The wrought-iron structure consists of 4 huge arched legs, assault masonry piers that curve inward until joining in a single, tapered tower.

Building the tower required 2.5 million thermally assembled rivets and seven, 300 loads of iron. To protect the tower from the weather, workers painted every inch of the structure, a feat that required 60 loads of paint. The tower has since been repainted 18 times.

Conclusion: 

The Eiffel Tower can get older to fifteen centimeters taller during hot Parisian summer days. This is due to “thermal expansion.” When an object is heated, its particles gain Kinetic Energy, move faster, and take up extra space. Most large structures like bridges (or the Eiffel Tower) are constructed with this principle in mind so that they can expand and contract a bit without breaking.
So, if you would like to climb the steps of the Eiffel Tower, go in the winter!
