I have a challenge dealing with aluminum foilI have a 6 inch by 9 inch sheet of aluminum foil which will be folded into whatever shape I like and put in waterThis sheet will then be given pennies until the sheet sinksWhat would be the best shape to use on the aluminum foil?Second question: Does the volume of water displaced by the boat relate to the weight of the penniesHow?
Sounds like itIt sounds somewhat mild, as most of these symptoms are still rational (When OCD gets real bad, most of your actions defy logic).
I am not a psychiatristhowever, my brother has ocdthis does sound alot like you have iti suggest you see a psychiatristi dont meen that in a mean waybut they are the specialists at this type of thingtell your momor if you are older, see a psychiatrist.
Well it all pretty much depends on your situationThis may not be from having OCD, maybe you are just under some sort of stress that causes you to want to do this stuff? Maybe your stressed out and this is the only way you can solve problemsMaybe try relaxing, and then see if your symptoms still appear.
definition: density Mass ( or weight) / volume water is about 1 gram per cubic centimeter the greatest density sinks an object displaces water that has a weight equal to the volume of water if the displaced water is Less than the total weight the object sinks so you are trying to make a boat of Al with air inside to hold heavy pennies the trick is to get the largest volume of boat with allowed area of Al ( assuming the the Al will not 'fold up what is the surface area A 6 x 9 but what is the best fold to get 4 sides and one bottomthat takes some rial and error and measurementshould it be a rectangle? what gets foldedany Al wasted by doubling over to make the cornersNOT so easy this is experimental engineering combined with some geometry of shapes this is the kind of problem an engineer faces, limited material, best choices, basic science
