| Parameter | Symbol | Description | Dimension |
| Force_on_Action_Marker |
| The acting force vector on the action marker is always zero. | Force |
| - Measure_in_Base_Marker |
| The acting force vector transformed into the reference frame of the base marker is always zero. | Force |
| - Measure_in_Action_Marker |
| The acting force vector transformed into the reference frame of the action marker is always zero. | Force |
| Torque_on_Action_Marker |
|
From Equation 4–11, the acting torque vector on the action marker can be calculated as follows:
Where, the vector | Force*Length |
| - Measure_in_Base_Marker |
|
The acting torque vector is transformed into the reference frame of the base marker as follows:
where, the variable | Force*Length |
| - Measure_in_Action_Marker |
|
The acting force vector is transformed into the reference frame of the action marker as follows:
where, the variable of | Force*Length |
| Force_on_Base_Marker |
| The reacting force vector on the base marker is zero. | Force |
| - Measure_in_Base_Marker |
| The reacting force vector transformed in the reference frame of the base marker is zero. | Force |
| - Measure_in_Action_Marker |
| The reacting force vector transformed in the reference frame of the action marker is zero. | Force |
| Torque_on_Base_Marker |
|
The reacting torque vector on the base marker can be represented as follows:
| Force*Length |
| - Measure_in_Base_Marker |
|
The reacting torque vector is transformed into the reference frame of the base marker as follows:
| Force*Length |
| - Measure_in_Action_Marker |
|
The reacting torque vector is transformed into the reference frame of the action marker as follows:
| Force*Length |
