A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded 1 s4 U" h5 j' }+ w7 o7 M- P1 U5.39.217.77 . e4 D1 _8 A; h/ b5 J1 H8 ]公仔箱論壇公仔箱論壇( N5 y% x: z$ F0 Y: ~9 M3 t5 ^ The Incredible Magdeburg Water Bridge in Germanytvb now,tvbnow,bttvb8 v5 |4 e: u; K: l& S5 O
The Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world.TVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。: c( Z4 p/ f: q% Z. `
The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. 9 @& {6 m, c: Z( Y; M0 U ?
