When a beer can is full, its vertical center of gravity is half the can's height. When it is partly full, its vertical center of gravity is somewhat lower. When it is empty, the VCG is again half the height of the can. When is the can's VCG at its lowest


Now we all know something about beer cans ! lets see how much ?

When there is as much beer left as the can itself weigh's

Right Mika


"The VCG of the beer can will be at it's lowest when the mass of the beer in the can equals the mass of the can !! above the level of the beer. At this point the VCG will be at (or very nearly at) the surface of the beer with slight variance due to the different densities. Any lowering of the level of the liquid will result in the mass of the can overcoming the mass of the beer and raising the VCG, Any raising of the level will result in the VCG tending toward full position VCG. The exact measurement of the point will depend on the material and thickness of the can and the density of the beer, higher proof beers having lower densities and therefore changing the VCG movement."

It is when you are laughing so hard at this Tread that it comes out your NOSE.

what can I say, I think applied math is cool

"Rule of thumb: When the VCG starts to rise, it's past time for a fresh Beer !

Actually, since the weekends are slow on this board. I enjoy a little science/math project. Got anything else a little more challenging, and maybe more directed towards boats?

"6" ok tell you what :

"I hereby volunteer to conduct empirical experiments on this matter and come up with exact measurements for any brand of beer desired. Simply send a case or two of any beer desired to my home address, and I will post the results as soon as possible. Please allow a few weeks for experimentation.

Steve1,
So do you suppose a "light" beer has a lower specific gravity than a regular "run of the mill" beer. How about ale's or that super shake of a beer, the guiness? I'll bet that bad boy is right up there with lead.

LOL Mika Thats it Guiness brewed with Jersey river water Gotta be a little on the heavy side !!

Best Regards
