Quiz: Does the bridge need to be engineered to carry the weight of the water or the water plus the weight of the ship? Why?
I'm going to say weight of the water only, because the ship displaces it's weight in water (ergo: buoyancy,) so the overall load stays equal.

/lolnerdyness getting in the way of the funnies.

Only the weight of the water.

<Physics advanced course>
The water which is displaced equals the mass of the ship, even though the ship floats and isn't completely submerged so the whole weight doesn't change when a ship goes over the bridge.

[IceBone] Surely the upper level is a canal not a river? (hope noone makes any remarks about my displacement) [/IceBone]

I wonder how many people think you need to account for the weight of the water and the ship, that means if you swim under a ship it crushes you :lol:

Yes, of course that is a canal, it seems it is the Magdeburg Water Bridge.

Btw: this isn't a phenomenon exclusive for Germany, there are many other navigable aqueducts where there is a need of crossing a natural river with a canal.

[edit]
I think the craziest navigable aqueduct isn't in Germany but in the UK: it is the Barton Swing Aqueduct. It's a trough filled with water which can be swung 90? so bigger ships can pass the river underneath. I think that's even more crazy than a ship lift which just goes up and down (well, the Falkirk wheel which is also located in the UK is a crazy ship lift, but at least it is balanced out so for the rotation only needs a 20 kW-engine...).
