Worked Example
Verified calculation
Given:
- Aft Weight Moment = 150000
- Forward Weight Moment = 90000
- Vessel Displacement = 400000
- Longitudinal Metacentric Height = 120
Expected Result:
- Longitudinal Trim Angle = 0.00125
Engineering Interpretation:
Under the given input conditions, the calculated result is: Longitudinal Trim Angle = 0.00125 rad.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
