The Madeburg Water Bridge and Learn to Differentiate


Learn To Differentiate


If your mind is focused on an insignificant incident, it can destroy your happiness if you allow it to. To feel happy, your mind has to be free of pains and misfortunes.

Learn to differentiate between productive thinking about problems as a means of solving them, and counterproductive dwelling on misfortunes which gains nothing positive and destroys your quality of life.

Have you ever seen a river over a river? AMAZING.....
 
 
Even after you see it, it is still hard to believe!
Water Bridge in Germany.   What a feat!
Six years, 500 million euros, 918 meters long . . . now this is engineering!

This is a channel-bridge over the River Elbe and joins the former East and
West Germany ,
As part of the unification project. It is located in the city of
Magdeburg , near Berlin .
The photo was taken on the day of inauguration . . . 

To those who appreciate engineering projects, here's a puzzle for you armchair engineers
. . .  and physicists. 

Question:

Did that bridge have to be designed to withstand the additional weight of ship and barge traffic,
Or just the weight of the water?
 
 

Answer:

It only needs to be designed to withstand the weight of  the water!

Why?
 
 A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded.

The Incredible Magdeburg Water Bridge in Germany

The Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal, and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world.
The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe. Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo.
Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997. The aqueduct was finally completed and opened to the public in 2003.
