Description
Ideal centered underbody breakover angle over a sharp convex crest; excludes wheel deformation and overhang.
A production plan combines stage geometry, cue times, movement distances, material dimensions, and explicit scheduling or accounting rules. Signed margins reveal surplus or deficit under the chosen model. Physical clearances, execution variability, and governing requirements can require checks beyond one arithmetic term.

When to use this tool
Use Touring Case Wheelbase Ramp Angle when you need this specific stage, cue, material, timing, count, or fee term under supplied production assumptions.
How to use the tool and how it works
- Enter wheelbase, clearance. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read breakoverAngleRadians. Use the output convention below.
For positive wheelbase and nonnegative clearance return breakoverAngleRadians=2*atan2(2*clearance,wheelbase).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| wheelbase | Wheelbase | Required. Finite number; strictly above 0. |
| clearance | Clearance | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| breakoverAngleRadians | Ideal symmetric breakover angle in radians, not degrees. | Required. Finite number. |

}Limitations and assumptions
- Lengths need one unit and the output is radians. This ideal symmetric breakover geometry omits wheel size, load shift, ramp transitions, caster movement, and safe handling of a touring case.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use a complete production schedule or equipment/layout assessment when one margin is insufficient. Check units, timing conventions, tolerances, and physical constraints before combining terms.
