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 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.

its amazing...
ReplyDeleteonly germans can do this..
what a technique...
like this kind of bridge is also in vettikadu ,a small village in tamilnadu,india but this was built by british may be in 1908 but that was smaller e\when compared to this.....
ReplyDeleteya. i agree to that thae ship displaces an amount of waterthat weighs the same as ship. but it is not possible in all bridges. if the bridge is very huge that ,if displaced water do not over flow than the bridge should take the weight of both displaced water and ship. here the displaced water means , the ship has taken place of water.SO I DO NOT AGREE.......
ReplyDeleteTrue Wonder of Engineering... Indian too have the capabilities to build even better..
ReplyDeleteHello my friend, everyone of you is right on your place, but let me tell you one thing,
ReplyDeleteIf you go to punjab, district Ropar, you will find more then 10 cross water bridges, mainly on bhakra nangal canal, and rajastan canal which comes out from river sutlej.
Try to find it out on Indian map you will find more amazing engg. stuffs in India

The bridge has to take care of the combined weight of the ships and water, as the displaced water does not overflow. If it was allowed to overflow, each time a ship crosses, the water level would keep on decreasing, adding complexity to the system.
ReplyDeleteThe Real question is - How are they holding water as a continuous channel much above the normal sea level. why the hell its not flowing down to its stable level !!!
