Why do you think that people use balsa wood instead of fir for making miniature airplanes?explain your answer.

Balsa wood is lighter and finely grained so it is less likely to break than more coarsely grained woods like fir.

Lumber is used in all sorts of construction, so it is always in high demand.\n\n"Pleztop's" response about paper is correct, but lumber is not used to make paper.  Lumber is created from cutting timber.  Timber by-products like wood pulp are the primary ingrdients in new paper.

How about Timber - wood, for ship building. Canada has lots of lumber and the Brits were really, really into ship building around that time.\n\nGood Luck

Simple. America is dumb and like to things the hard way. Or the material is really expensive that companies don't want to buy enough to make the whole plane. The only other reason I can think of is that it is heavy, but then again, we managed to get metal to fly and float.

As per the CTI(Cooling Tower Institute) www.cti.org, - douglas fir is the main softwood used in part due to its strength. Some towers are made out of redwood and that is because of redwood's treatability(now most redwood is sapwood) and appearance.

That is a good question.  Trees are a renewable resource though, so it is kind of a non-issue.

the metal part?  or the airbrush part?  you really need to explain the question a bit better.

Carpeting is less expensive than hardwood flooring.  As for making the home warmer - that must mean aesthetically, not temperature wise.  Neutral is a selling point because any furniture will go w/ it.

you should use fiberglass not wood. its what all of the new ones are made out of. it might be harder to make it out of fiberglass though.

Most modern sticks are made from fiberglass/aluminum or carbon fiber.  These come in either one or two-piece.  Two-piece sticks allow you to snap the blade and replace it without scrapping the whole stick.  The blades are made of wood, fiberglass, carbon, or any combination there of.  The most common wood used today is White Ash and Birch.\n\nOne piece carbon sticks are made from the inside, out.  They layer carbon fiber over and over.  Each layer gets a coat of epoxy.  This is what makes it hard.  The epoxy has very little strength and the carbon is strong but flimsy.  Think of carbon fiber as fabric and the epoxy as peanut brittle (stay with me).  If you took a slapper with just an epoxy stick, it would shatter.  If you took a slapper with just a carbon fiber stick, it would flap in the breeze.  The combination of the two gives it unbeatable strength yet still allows it to flex a bit.\n\nOld wood sticks are still around, but the preferred wood (Rock Elm) is becoming scarce.  Dutch Elm disease has wiped out most of the supply.  So now manufactures are turning to White Ash.  It's not as strong, but it's about 1/4 the price of Rock Elm.

Ah, the Spruce Goose was the largest airPLANE ever built. More on that  story below. This person asked about the largest airCRAFT ever built, which would be a dirigible.  "Ended in disaster" must mean the Hindenberg!  I am not sure if the Hindenberg was the absolute largest dirigible, but it certainly was one of the largest. The Hindenberg burst into flames upon docking in New Jersey someplace in the 30's and pretty much ended the Dirigible business. That incident is where we get the phrase "Oh, the humanity!"  which is often mocked, in my opinion inappropriately. That is an interesting whole story itself but is off topic.\n\n\nThe Spruce Goose: During WWII, metals were in short supply;  all those battleships and overseas ore shipping routes inaccessible, I suppose. So, Howard Hughes' aircraft company was encouraged by the government to try and build aircraft from alternative materials.  Wood is light and strong, so it was a natural thought.\n\nProblem is, one piece of wood can have a very different density and even strength than another. Doing the structural analysis on such a craft and keeping it balanced is an absolute NIGHTMARE.  I don't know if the spruce goose itself ever flew but it was a prototype and the conclusion of this engineering study was that this wood idea was impractical for large aircraft. \n\nNo doubt you can find more details on The Hindenberg, The Spruce Goose and "Oh, the Humanity!" in wikipedia.\n\n(This is not quite an Astronomy question.)

It seems research on this has continued. Still sounds very preliminary though - experiments on small models or paper planes ;)  But maybe you'd like to check the links.

Pipe makers use briar wood!\nIt is very hard and very hard to get!

They are hand made from excellent and expensive wood.  The wood pieces must be structurally perfect in large sizes and are rare.  They take FAR longer to make than any other instrument.\n\nThe cheap plastic ones aren't that much more than other instruments.  Also, they are far less popular, so there is a volume/demand issue as well.

Probably check out a hobby store that may have models that meet your needs.  \n\nThere are simple planes made of balsa or heavy paper you could make from scratch (without a kit).  It just depends on your skill level, ambition, and what you need it for.

Back in the day, hockey sticks were made from Rock Elm.  This wood was preferred because it was so strong yet light.  Since the Dutch Elm disease outbreak in the early 90's wiped out most of the supply, manufactures changed to White Ash (same thing most baseball bats are made of).  It's not as strong, but it's about 1/5 of the cost.\n\nIt's pretty rare to find a wood stick nowadays - sometimes wood blades, but not a wood stick.  They make the sticks in a very similar way to baseball bats.  The manufactures find a very straight grain in a piece of wood, cut to the desired length, and cut out a notch (hole) for the blade.  A wood, wood/fiberglass, or carbon composite blade is then inserted in the notch.  It's pretty rare to find a one-piece wood.  These were extremely expensive to make, and if you snapped your blade,  the whole stick had to be junked.  Two-piece designs allow you to snap the blades all you want and still re-use the same stick over and over.\n\nHowever there isn't much to a one-piece wood stick.  The manufactures took a larger diameter tree and cut with the grain and across the widest part of the tree for the blade.  This process would yield about 2 one-piece sticks for every 6' of wood.  Not too efficient.

I know they had some flying toys as kids - i.e. rubber band helicopter sort of things. Also it was sort of a craze at the time, google early aviation history or equivilent and you should be able to find some videos and other info.
