## What is The Center of Gravity Calculator?

In engineering, we can deal with both 2D and 3D calculations. Also, 2D calculations require only 2 coordinates to obtain the center of gravities of masses or mass systems. But 3D calculations require 3 coordinates X, Y, and Z.

Calculation of the center of gravity of mass systems is not a hard business with hand. But for a very high number of masses, it can be troublesome and time-consuming. So, you can use this center of gravity calculator to calculate complex center of gravity problems.

## How To Use The Center Of Gravity Calculator?

Firstly, you need to select 2D or 3D options. If you are dealing with 2D plane masses, you need to select 2D. And if you are dealing with 3D space masses, select 3D.

**If You Select 2D;**Enter the number of masses that your system has. You can also divide a complex-shaped system into more basic multiple masses to calculate the center of mass of that system. You need to enter, how many masses you have in your system.

Then you need to enter the mass, X, and Y coordinates of the center of gravities of these sub-masses respectively. If you click on the 'Calculate!' button, the center of gravity will be calculated.

After that, the Center of gravity will be given in X and Y coordinates.

**If You Select 3D;**Actually, the difference of the 3D center of gravity calculation is the additional Z coordinate. You need to make the same steps with 2D with an additional Z coordinate.

So the Center of gravity will be given as in X, Y, and Z coordinates.

## Conclusion

So, there is no limit to entering sub-mass numbers. Similarly, if you have a complex system to calculate the center of gravity, you can divide this system into more basic and geometrical masses to calculate the center of gravity of the whole system.

Above all, Mechanicalland does not accept any responsibility for calculations made by users in calculators. A good engineermust check calculations again and again.

## 2 responses to “Center of Gravity Calculator”

Either I don’t understand how it works, or the CG calculator doesn’t work right.

For 3 masses in 2D, in a system of reference, I have:

Mass A: 2 kg, X=10m, Y=10m

Mass B: 3kg, X=20m, Y=10m

Mass C: 6kg, X=15m, Y=50m

I put this in and I get the coordinates of the center of gravity:

X=4.7222

y=9.7222

In the system of reference I used that doesn’t even fall inside the triangle formed by the three weights. It makes no sense.

What’s the story?

Hello Hiro,

Thank you very much for warning us and providing detailed information.

We found that there was an issue that we reviewed your alert for. The problem was that there was a problem with the inputs that we used through the browser, not the calculation. Thanks to your warning, we noticed this situation and fixed it.

You can try the Center of Gravity Calculator operation again. Don’t forget to come back to us, smile 🙂

As the Mechanicalland team, we thank you.
