Sometimes I think there's a lack of a forum section on building physics.

A place to discuss general thoughts and questions about material properties and things like sound, moisture, forces, and load-bearing capacity, etc., etc. When the question or post is not directly aimed at walls, or roofs, or patios, or...

However, I think the subject is too narrow to need and/or benefit from its own forum category. I'm bringing up the question to see if there are others who think like I do.

Where does the light go when you turn it off? ;)

Can't really say I've missed such a forum, even though physics interests me.

And where does the white color go when the snow melts? :)


Yes, a subforum "building physics" risks becoming pitifully small, perhaps unjustified to have its own subforum.
Maybe a pinned thread pointing to topics that cover such things?
But then the question becomes where the pinned thread should be. ;)

Does a candle burn up or down?

I also find it interesting, but I think it might be a bit too narrow of a topic. Maybe it would be better to tag the subject? (But then again, you tend to forget that....):o
 
I think such a forum under miscellaneous would be interesting. There is a relatively high proportion of engineers on BH.

Certainly, there are many threads that already touch on these directions, but they are anything but easy to find.

In the meantime, we can ponder some popular physics, like why does the fire on a matchstick go out when you blow on it, while it flares up when you blow on a glowing charcoal piece?
 
Building physics it was, guys...

Wind loads, snow loads, reinforcement, bearing capacity in lightweight concrete, etc., were things I struggled with when I last built. A small collection of links would have been worth gold.

But for now, you can ponder how a liquid burns in a spaceship where there is no gravity. ;)

Good idea!

Maybe as a subforum to building materials and building technology.
 
Such matters have always been discussed in Byggmaterial&Byggteknik and that's exactly what this section is for - I think this works excellently as it is. No thank you to more subforums, yes please to more discussions about byggfysik.

fart !!! :mad:

I wrote a long post.
I realized I wanted to format it a bit, so I clicked in the "noscript plugin" "allow byggahus.
Then it lets the page reload, and poof, everything I wrote was irretrievably gone... :mad:

Oh well, maybe I'll have the energy to rewrite it, or in a shorter version. :|

If you had allowed scripts, there would have been a function that autosaved the post for you every 30 seconds,

*sprinkles salt in the wound* ;)

No, but sorry, it's always just as frustrating when the browser eats the texts you've written.

Edit: And to not be completely off topic: As a former engineer wannabe, I think such a forum sounds exciting!

Thanks for the salt. :|
;)
Yes, it is the unholy alliance between FF and NoScript that automatically reloads the page when I change any rule for NoScript. I should have thought of that, as it was not exactly unknown to me. :mad:


Anyway.
I'm thinking about writing something general about sound and soundproofing.
When I choose to post it, I might select "Insulation" or "Building Materials & Construction Techniques," but since it's about walls and ceilings, maybe "Timber Frame & Log Houses" or "Roof & Attic" would be more suitable. Then there will probably be some talk about windows and doors too, "Windows & Doors." It might include some information about the properties of concrete "Stone Houses," and regulatory requirements, etc., "Environment & Health" or "Building Permits."
Then I might mention something about noise sources, "Kitchen," "Laundry Room," "Technology," or appliances.
Or how to muffle the lawnmower "Garden Machinery."

You see the problem?

The problem that I'm just thinking about writing something up, meaning it never gets done :x :o :|

But I do agree with MathiasS and others. "Building Materials & Construction Techniques" is probably the right placement for such a general thread.

Hmm, there should be no convection. That is, it burns much slower and there shouldn't be a flame in the same way but rather like a burning "ball". Maybe?
 
The subforum Building Technology is not terribly large, and I think building physics fits quite well under that category. Perhaps it's enough to adjust the text on what is included under this subforum?

Gold star! :thumbup:

At least that's what the guys at NASA told us. Firefighting in space is reportedly really tricky. Hard to get the foam to stay on top, etc..

Can't they just open the door and let the fire out if it starts burning? Just a little ajar, you know.
