Sum of Forces Magnitude (FM)

Returns the magnitude of the net translational force acting at one coordinate system marker due to all applied forces and constraints acting between that coordinate system marker and another.

Format

FM (Applied To Marker, Applied From Marker)

Arguments

 
Applied To Marker
(Required) Measure the sum of all forces applied to this coordinate system marker.
Applied From Marker
(Optional) Measure the sum of all forces applied from this coordinate system marker. If you don’t specify this argument, it returns the magnitude of the net translational force at the Applied To Marker due to action-only single-component forces acting at the Applied To Marker.

Equation

Mathematically, FM is calculated as follows:
where:
is the sum of all applied and constraint forces involving both the Applied To Marker, T, and the Applied From Marker, F.

Example

The following function returns the magnitude of the sum of all forces acting at marker_T. All forces acting between marker_T and marker_F are included in this calculation:
