Description
Multiply partMass/positive totalMass by signed displacement for shift and add it to originalCenter.
Ideal product geometry maps dimensions into lengths, areas, or coordinates under a stated shape model. A dimension ratio does not by itself establish manufacturability, strength, or usability.
Multiply partMass/positive totalMass by signed displacement for shift and add it to originalCenter.
When to use this tool
Use Product Center Mass Shift One Part when you need one explicit product-geometry component.
How to use the tool and how it works
- Enter totalMass, originalCenter, partMass, displacement. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read newCenter, shift. Use the output convention below.
Multiply partMass/positive totalMass by signed displacement for shift and add it to originalCenter. Require partMass within totalMass.1
| Input field | Meaning and units | Accepted input |

| totalMass | Total Mass | Required. Finite number; strictly above 0. |
| originalCenter | Original Center | Required. Finite number. |
| partMass | Part Mass | Required. Finite number; minimum 0. |
| displacement | Displacement | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| newCenter | New Center | Required. Finite number. |
| shift | Shift | Required. Finite number. |

}Limitations and assumptions
- This assumes one existing part moves without changing total mass or other parts; it is a one-axis center-of-mass shift, not stability analysis.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
