if it floats, it would displace 10000000 tons of water, which would spread over the entire surface of the canal, perhaps raising the water level in the entire canal by 0.0001mm and the water pressure over the bottom of entire canal by an imperceptible amount

Water displacement.

anyone?
Provided the barge moves through at a steady speed, and keeps a straight course, then the effect will be virtually nil.
If the barge were to veer from side to side, as it passed through, then it would put a impart a small force to each side, as it veered to that side.
I,m sure the designers would have allowed for this.
What you have to remember is, if the barge weighs 10,000lb, it displaces 10,000lb of water, which will even out over the whole canal system.
It is exactly the same as removing the barge and pouring 10,000lb of water into the canal.
The only force the barge can impart, is by water movement. But at the speed barges travel this will always be quite small
I have an enormous tank of water and its depth is constant through out.
it sits on a weigh bridge.
i can weigh the tank and the water and it weighs X.
i lower a barge onto the water and the barge floats also it weighs Y.
please tell me what weight the weigh bridge records.
i then pull the bung in the bottom of the barge so that it sinks.
pleased tell me now what the weigh bridge records?

Trazor thats not how archimedes principle works mate.
The weight will be X+Y, that is tank , water, and barge together.
As the system is closed the total weight will still be X+Y.
You proved earlier in the thread that you did not understand the principles involved................................Mate
to simplify the canal argument, the weight of the barge will displace the amount of water it weighs
the viaduct in theory sees no difference in weight provided the displaced water can flow evenly across the entire canal system it would merely raise the water level slightly if the canal system is big enough then the viaduct will see a negligible difference in weight as the barges weight is spread over the entire surface tension of the water in the canal system (remember water finds its own level)
my earlier attempts at humour (that failed dismally im afraid
) were what if you displaced enough water that its level went over the sides until there was no water left? then the viaduct would collapse if its structure wasnt strong enough to take the barges weight alone.

sorry and i wasnt attempting derogatory sarcasm.
mass does not displace its own weigh in water, it displaces its own volume, thats when archemdes screamed
geez this water is too fooking hot
look i dont make the rules okTim, you are in big trouble, if you have a barge on a VIADUCT...........
but its weight has to be carried otherwise it sinks and water being what it is spreads this across its entire surface surely? bit like putting boards across a flat roof to even out the weight of a person on it
