where can I get a vehicle weighed?

[rgutsell]

Hiya all

Does anyone know where I can get a campervan weighed?

Probably a scrap yard or freight depot

[lameduck]

there are usually weighbridges on council amenity sites

like the local refuse site Devon road / churchfield road Beckenham or scrap metal yards Grove street Deptford

anywhere that you would use a vehicle and be charged by weight etc.

Contact VOSA they have some sites, otherwise some tips have them

I get my van weighed when I go to the tip at Devon st (off old Ken road). So they should be happy to weigh your car if you ask nicely!

If you put it in a bath full of water you can measure the displaced water.

Campervantastic in Forest Hill might be able to help.

0/10 for physics, TED. That's the volume, not the weight.

If you haven't got a big enough graduated flask you could drive it off the end of a pier and see how far the water comes up the beach.

Another way might be to drive it very fast into a church and see how hot the fireball gets - it will be proportional to the kinetic energy in the system, which is itself a function of mass and velocity using the formula ? mv?. For the purposes of this calculation you could ignore the speed of the church.

If you want to keep it in one piece (you don't mention this) you could perhaps tie a stout rope around it and tie the other end to a bollard. If you knew the breaking strain of the rope (a good hardware store should be able to tell you), you could calculate how fast you had to drive around the bollard before the rope snapped. At this point you could calculate mass using the formula F = mv?/r, where F is the breaking strain of the rope, r is the length of the rope, and v is the speed you were going when it snapped.

Loz, if you assume the van was lighter than the water it displaced, then as it floated the mass of water displaced would equal the mass of the van.

If the van sank, you'd be buggered unless it was in a very deep part of the ocean where the density (and hence mass) of the water rose appreciably with depth. The van would sink until buoyancy was achieved at a particular depth (and hence density and mass).

Almost right. But. actually the arcimedes principle relates to weight. I got my physics o level! Its not volume! Just noticed hugs explained better than me.

[DulwichFox]

Look in the Log book .. Should tell you the weight.

Google the model and check specs.

Damn - only looked in to see if Salsaboy had done a "Whayhaaay!" gag yet...

Hallo all

Thanks for your suggestions, ideas, and insights.

Luckily, the population is not dependant upon the scientific knowledge of residents in ED.

I am going for the Local Amenity idea, then VOSPA.

I'll be back ( as Arnie Schwarzenneger said!)

I know a poor qulity joke regarding a suitable place to get the weight of your pet cetacean confirmed, but I cant be arsed.

Weight of the water displaced, not the weight of the vehicle. As Hugo said, if the vehicle sunk (most likely) you wouldn't know it's weight.

The whole 'Eureka' story was that Archimedes knew the weight of the crown (?), but he didn't know its volume. So, he could not calculate the density and therefore decide if it was made of gold or not. But, once he stuck his fat backside in the bath...

Dunno about that joke, but I did hear about the oyster dancing rather vigorously at the disco. He pulled a mussel.

oh go on then...

you go to a "whale-weigh" station.

lol rofl omg wtf lmfao

[the-e-dealer]

for a floating object on a liquid, the weight of the displaced liquid is the weight of the object. Thus, only in the special case of floating does the buoyant force acting on an object equal the objects weight.
