Hello all, and thanks in advance for your assistance.


I have an empty metal cabinet design. It is made of 5052-H32 Aluminum. I would like to assign the density so I can get an understandable total weight of the cabinet.


Currently this is what is reported by the Model Mass Properities:


VOLUME = 1.8822252e+03 INCH^3


SURFACE AREA = 3.0173937e+04 INCH^2


DENSITY = 9.7912060e-02 POUND / INCH^3


MASS = 1.8429255e+02 POUND


I would like to decipher this and understand what it's saying. If I need to change the density and you know what the density value should be for 5052-h32 aluminum, I would appreciate you letting me know what the correctvalue should be. + any other info you think you should supply.


Thanks again for your assistance,


SrG
 
I have aluminum at .0975 lb/cu in.


Your part has it at .00979 lb/cu in.

9.79xxx-02 = .0979

did you mean 9.79xxxe-2
 
Your density should be .097 lb/cu in. (in pro DENSITY = 9.7000000e-02 POUND / INCH^3). Your volume is 1.8822252e+03 INCH^3 (which is 1882.2252 cubic inches). Giving you a mass of 182.576 lbs.

Edit > Setup > Density to change the density of your part. Providing your density is correct then all your mass properties will compute correctly. Don't forget that Pro/E is only capable of computing mass by the density. Pro/E is only aware of volume.


mass = Rho x volume
 
All of this is much easier in metric land. A cube of 1 dm makes a volume of 1 dm3 and if it is water then density is 1 so the weight is 1 kg. Life can be so simple ...
 
It's not water though is it? It's aluminium?

Then take 2.7 for density.
