*SetForce() - symmetric rotational

Sets the values for a symmetric rotational action-only or action-reaction force (torque) pair.

Syntax

*SetForce(force_name, LEFT|RIGHT, LIN, value_tx, 
                                            LIN, value_ty, 
                                            LIN,value_tz)

Arguments

force_name: The variable name of an existing rotational action-only or action-reaction force pair.; Data type: varname
LEFT RIGHT: If LEFT is specified, the properties are assigned to the left force, and the right force properties are made symmetric to the left force.; If RIGHT is specified, the properties are assigned to the right force, and the left force properties are made symmetric to the right force.
LIN: Keyword suggesting that a linear value is used to specify the force value. With symmetry, only LIN is valid.; Data type: keyword
value_tx, value_ty, value_tz: Numbers or MDL expressions that determine the values of the rotational force about the X, Y, and Z axis of the specified side of the force pair.; Data type: real

Example

*BodyPair(b_wheel, "Wheel body")
*PointPair(p_wc, "Wheel center")
*ActionOnlyForcePair(frc_wc, 
 "Applied force on wheel center", 
 ROT, 
 b_wheel, 
 p_wc)
*SetForce(frc_wc, LEFT, LIN, ds.real1.value * ds.real2.value, 
 LIN, 10.3, 
 LIN, ds.real3.value)

Comments

Solver expressions, curve data, or user subroutines cannot be used for symmetric force pairs.
