Thanks Bryan,
Really great Timesaver.

what’s the equoation behind it?

Hi Bryan

Looks like a cool tool that I may be able to use. Do you do any hand holding?

I have an industrial application, but no real understanding how to apply your calculator to my situation. I could use a diagram in a form I would understand and apply.

Up for working with a pure novice?

Thanks Bryan, this was a timesaver.

Great little program! Thanks a lot!
If you’re ever bored, a reverse calculator would be also be useful. (Specify COG and (position or weight)and it fills in the blanks.

Awesome program! Thanks a lot!

For those of you trying to use Z-coordinates, just do two calculations of center of gravity: one on the XY plane and the other (and as I find it easier to do), on the YZ plane following the right hand rule. Then, combining those (not averaging any of the values), you have your center of gravity in the 3-coordinate system.

Hello

Thanks for the program it is great!

But where do you have the Z coordinates

I think you can calculate 2 times where second time is x or y is z, but is not exact
Do you have possibility to put inn z coordinates in you program ?

Is something wrong?
One mass cg @48,0″ 300lbs. second mass cg @.5,0″ 100lbs. I entered this data:
w:300,100
x:48,.5
y:0,0
result = 37.25,0
I then want to add more of the second mass, 2x mass and 2x cg. entered data and get this:
w:300,200
x:48,1
y:0,0
result = 29.2,0
But when I add a third of the second mass 3x mass and 3x cg, total cg moves away from O.
w:300,300
x:48,1.5
y:0,0
=31.5,0
Add 4x mass and 4x cg, total cg moves back towards O.
w:300,400
x:48,2
y:0,0
=21.714285714286,0

Hi, I have a homewwork to find center of gravity, given weights, distance and Dollar per mile. Do I have to consider Dollar per mile while calculating center of gravity. I think including dollar per mile would make more sense. Am I right?
