*ActionReactionForcePair() - line of action

Creates an action-reaction translational force pair acting along the line joining the points of action and reaction.

Syntax

*ActionReactionForcePair (force_name, "force_label", LOA, body_1, body_2, point_1, point_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
LOA: This argument indicates the action-reaction translational force pair acts along the line joining point_1 and point_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 on body_1 at which the action force pair is applied.; Data type: Point or PointPair
point_2: The point or point pair on body_2 at which the reaction force pair is applied.; Data type: Point or PointPair

Example

*PointPair(p_jnc_frame, "Jounce bumper pt on frame")
*PointPair(p_jnc_axle, "Jounce bumper pt on axle")
*Body(b_axle, "Axle", p_axle_cg)
*Body(b_frame, "Frame", p_frame_cg)
*ActionReactionForcePair(frc_bmp, "Jounce bumper force", LOA, b_axle, b_frame, p_jnc_axle, p_jnc_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 LOA is used to apply action-reaction force pairs on two bodies or body pairs along the line joining two points at which action and reaction forces are applied.

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