Subject: COOL BRIDGE

 

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. 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 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. Remember  your high school physics, and the fly in an enclosed bottle project? Similarly, the super sensitive scale proved that it didn't make any difference whether the fly was sitting on the  bottom, walking up the side, or flying around.  The  bottle, air, and fly were a single unit of mass and always weighed the same.
