[BITList] RIVER OVER A RIVER !

[franka]

Water Bridge in Germany
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.
