Have you ever seen a river over a river?...
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.
