Calculating weight

[SrGilberto]

Hello all, and thanks in advance for your assistance.


I need to know the weight of a model.


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


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

HI,


If u want to change the density for the particular part, just open that and go to edit - setup - mass properties. There u can change the density of the particular part.

The density you list is about right for aluminum. I've seen it from .096 to .098.

What you're looking at is scientific notation. The e## just tells you how to shift the decimal to see the real number. "e" with a positive number following means that you shift the decimal that many places to the right. "e" with a negative number means you shift the decimal that many places to the left. Of course, "e" with a zero following means the decimal doesn't move.


VOLUME = 1.8822252e+03 INCH^3 means that you move the decimal 3 places to the right. So,the volume is1882.2252 inch^3.


SURFACE AREA = 3.0173937e+04 INCH^2 means that you move the decimal 4 places to the right. So, the surface area is 30173.937 inch^2.


DENSITY = 9.7912060e-02 POUND / INCH^3 means that you shift the decimal 2 places to the left. So, the density is 0.097912060 pound / inch^3, which JamesM points out is aboutrightfor the normal density assigned to aluminum.


MASS = 1.8429255e+02 POUND means that the mass is 184.29255 pounds.


Hope this helps.

SrG, when you enter the density of a part in Proeng like described above you enter it as specific gravity/specific weight ratio.
