# Calculated Masses

How to view masses calculated from the load combination used for frequency analysis.

Tables > Masses > Calculated Masses prompts you with the following dialog.

![](https://560001759-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FWNe8U6EBBBdUJHdb2X9G%2Fuploads%2Fgit-blob-fa7dff3ec0a87754178281ece54eb8af344a6490%2FCalculated%20Masses.png?alt=media)

It allows you to view the masses calculated from the load combination for frequency analysis set in Analysis > Frequency Analysis. The program will automatically convert all forces (not moments) in the positive or negative gravity direction to masses and apply them in all available mass degrees of freedom.

Obviously, the calculated mass values cannot be modified. However, you may convert all the calculated masses to additional masses. In this case, the “Convert loads to masses” option in Analysis > Frequency Analysis will be disabled. This technique may be useful when you want to account for the influence of axial loads on frequencies.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/e3d-user-manual/interface/toc175916526/input-data/masses/toc161393919.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
