A River Over A River ?

Published on December 16, 2010   ·   No Comments

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.
