This information is part of the Modelica Standard Library maintained by the Modelica Association.

The cut-torque acting between the two frames to which this model is connected, is determined and provided at the output signal connector torque (= frame_a.t). If parameter positiveSign = false, the negative cut-torque is provided (= frame_b.t).

Via parameter resolveInFrame it is defined, in which frame the torque vector is resolved:

resolveInFrame = Types.ResolveInFrameA.	Meaning
world	Resolve vector in world frame
frame_a	Resolve vector in frame_a
frame_resolve	Resolve vector in frame_resolve

If resolveInFrame = Types.ResolveInFrameAB.frame_resolve, the conditional connector "frame_resolve" is enabled and output torque is resolved in the frame, to which frame_resolve is connected. Note, if this connector is enabled, it must be connected.

In the following figure the animation of a CutTorque sensor is shown. The dark blue coordinate system is frame_b, and the green arrow is the cut torque acting at frame_b and with negative sign at frame_a.

resolveInFrame	Value: Modelica.Mechanics.MultiBody.Types.ResolveInFrameA.frame_a Type: ResolveInFrameA Description: Frame in which output vector(s) is/are resolved (world, frame_a, or frame_resolve)
animation	Value: true Type: Boolean Description: = true, if animation shall be enabled (show arrow)
positiveSign	Value: true Type: Boolean Description: = true, if torque with positive sign is returned (= frame_a.t), otherwise with negative sign (= frame_b.t)

Nm_to_m	Default Value: 1000 Type: Real (N·m/m) Description: Torque arrow scaling (length = torque/Nm_to_m)
torqueDiameter	Default Value: world.defaultArrowDiameter Type: Diameter (m) Description: Diameter of torque arrow
torqueColor	Default Value: Modelica.Mechanics.MultiBody.Types.Defaults.TorqueColor Type: Color Description: Color of torque arrow
specularCoefficient	Default Value: world.defaultSpecularCoefficient Type: SpecularCoefficient Description: Reflection of ambient light (= 0: light is completely absorbed)
