Water displacement.

[WDIK]

well thats true if you think that laterally, however what if the canal is only as long as the via duct Hmmmmmmmmm

 

[Trazor]

the bouyancy and mass are different and irrelevant in this case.
the weight will tranfer to the viaduct.
wether the object floats or sinks.
its density dictates wether it floats or sinks.
if the mass of water displaced by the object is greater than the mass of the object then an upward thrust equilvalent to the mas of water displaced is exterted on the object so the level of bouyancy is equal to the mass of displaced water minus the mass of the object.

No.

If it floats, it merely displaces the same weight of water as the barge weighs.
If the barge weighs10,000lb, it will displace 10,000lb of water, which will then be evenly distributed through out the canal system.
The extra weight on the aqueduct will be very small.

If it sinks, it will only add weight directly to the aqueduct, by the extra amount added to make it sink.

JohnD beat me to it..................

That's why there are never lock gates either side of an aquaduct

with respect if that were the case then the object would be neutrally bouyant.

as i said, an object displaces a volume of water equivelent to its physical size,
ie if its 1 cubic meter and it is physically held under the water it will displace 1 cubic meter of water, if the object weighs less than the weight of a cubic meter of water then it will float, more and it will sink.

as i said, an object displaces a volume of water equivelent to its physical size,

No, a barge will only displace, about a third of its physical size.

@ WDIK

you're pulling our legs

naughty i didnt say barge i said object.

quote the statement not a selective part.

Doesn't matter, you are still wrong.

This thread is about an object floating in the water. a floating object displaces water equal to its own weight, not its own volume.

 

[Trazor]

OK, without being selective

with respect if that were the case then the object would be neutrally bouyant.

No, an object is neutrally buoyant when its density is the same as the water its in. To float a barge displaces its own WEIGHT.

as i said, an object displaces a volume of water equivelent to its physical size

Just what has this got to do with barges.

ie if its 1 cubic meter and it is physically held under the water it will displace 1 cubic meter of water, if the object weighs less than the weight of a cubic meter of water then it will float, more and it will sink.

Correct.

not so, its equivelent to the weight of water it displaces

 

[WDIK]

the bouyancy of of an object is now equivelent the the upthrust in weight of displacement of gin and tonic hic

Ah! but would it take off?

wrong it displaces its volume not its weight

possibley

Only if you fitted wings to it.
