*ActionReactionForcePair() - single component rotation

Creates a single component action-reaction rotational force (torque) pair acting about the given axis.

Syntax

*ActionReactionForcePair(force_name, "force_label", SC_ROT, body_1, body_2, point_1, {POINT VECTOR}, {point_2 vector_2)

Arguments

force_name
The variable name of the action-reaction force pair.
Data type: varname
force_label
The descriptive label of the action-reaction force pair.
Data type: label
SC_ROT
This argument indicates the action-reaction rotational force pair acts about the line joining point_1 and point_2 or about vector_2 .
body_1
The body or body pair to which the active force pair is applied.
Data type: Body or BodyPair
body_2
The body or body pair to which the reactive force pair is applied.
Data type: Body or BodyPair
point_1
The point or point pair used for defining the rotational axis.
Data type: Point or PointPair
POINT | VECTOR
A keyword that indicates the alignment method.
point_2 | vector_2
An entity variable referring to a Point, PointPair, Vector, or VectorPair which is based on the above keyword.
Data type: Point, PointPair, Vector, or VectorPair

Example

*PointPair(p_jnc_frame, "Jounce bumper pt on frame")

i MarkerPair The marker attached to b1.
j MarkerPair The marker attached to b2.
l ActionReactionForce Left force.
label string The descriptive label of the action-reaction force pair.
r ActionReactionForce Right force.
state boolean Control state (TRUE or FALSE).
varname string The variable name of the action-reaction force pair.

Comments

*ActionReactionForcePair() of type SC_ROT is used to apply action-reaction force pairs on two bodies or body pairs about the line joining two points or about a given vector.

The individual forces of an *ActionReactionForcePair() can be referred to as force_name.l (left force) and force_name.r (right force).
