X1 refers to the longitudinal positioning of the wheel locations, and it's essential to define the front wheel of the vehicle at X1=0. Y denotes the transverse placement of the wheels, which typically have a spacing of 6 feet between them.

X2 is used to define the range of variation in the location of the axle between two points. X1 indicates the starting point, while X2 indicates the endpoint. If X2 is set to 0, there is no variation in the position of the axle. For instance, the last axle's location varies between 28 and 44, as shown in the above screenshot.

## 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.openbrim.org/templates/steel-tub-girder-bridge-workflow/loading-stg/loads-stg/inf-surf-based-llbrce-stg/vehicle-stg.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.
