What is the kPa (or psf) of metal furring as a ceiling dead load?

AI Thread Summary
The discussion centers on determining the dead load value for metal furring in a roof truss analysis, with the only known value being 0.12 kPa for wood furring. Participants suggest looking up furring channels and provide a catalog link for drywall finishing products. One user decides to use a design load of 13 psf for white marble metal furring. Additionally, there is an unrelated inquiry about the color differences between national white marble and natural black marble. The conversation highlights the challenges in finding specific load values for construction materials.

I'm working on my analysis of roof truss assignment and got stuck on the computation of dead loads having no value for metal furring load. I only have the value for wood furring which is 0.12 kPa. I've been searching in the internet but still I'm not able to find it. Thanks in advance.

Here is a catalog of various drywall finishing products:

You can also look up 'furring channels' for the metal furring products if the items in the catalog do not suit your purpose.

Thanks for the link!
I'll use 13psf for design load.
 
White marble metal furring

I would like to know what is the reason of national marble color whit and natural marble color black
thanks

Thread '2:1 Pulley Question'

I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...

Thread 'Why do all my clocks run slow?'

Hi. I noticed that all electronic devices in my household that also tell time eventually lag behind, except the ones that get synchronized by radio signal or internet. Most of them are battery-powered, except my alarm clock (which runs slow as well). Why does none of them run too fast? Deliberate design (why)? Wrong temperature for quartz crystal? Decreasing battery voltage? Or just a coincidence?
