Have you ever seen a river over a river? AMAZING.....
你見過一條河流過另一條河嗎？ 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 your 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.

即使你看到它，它仍然是很難相信！
水橋在德國。多麼的壯舉！
六年來花費，500萬歐元， 918米長。 。 。現在這是完成的工程！
這是一個通道橋在易北河和加入前東德和西德，由於部分項目的統一。它位於城市馬格德堡附近的柏林。
該照片攝於當天的就職典禮。 。 。
對於那些誰欣賞工程項目，這裡有一個難題的工程師為您的扶手椅。 。 。和物理學家。
問題：難道是橋樑設計必須承受額外的重量船舶和駁船運輸，或者僅僅是重量的水？
答：它只需要設計承受重量的水！
為什麼呢？
船舶總金額取代水的重量一樣的船，無論怎樣嚴重的船舶可裝載。

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.
