Something Interesting on a Thursday Morning

My good friend Lu over at Lu's Bloody Big Book Blog just sent me this very interesting email and I thought I'd share it with you...

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.
