Components for Pin Connection Reaction Measures
A pin connection allows rotation around one axis. You can measure one of the following quantities for pin connections:
• Axial force—The component of the force in the direction of the axis of rotation (Z).
• Axial moment—The moment around the axis of rotation (Z).
• Radial force—The magnitude of the force in the plane perpendicular to the axis of rotation. This works to pull the two rigid bodies connected by the pin towards or away from each other.
• Radial force X—The component of the force in the X direction.
• Radial force Y—The component of the force in the Y direction.
• Radial moment—The magnitude of the moment in the plane perpendicular to the axis of rotation. This moment works to tilt the pin connection axis away from its defined position.
• Radial moment X—The X component of the moment in the plane perpendicular to the axis of rotation.
• Radial moment Y—The Y component of the moment in the plane perpendicular to the axis of rotation.
When you select the pin connection and any component other than Radial force or Radial moment, a colored arrow appears on the connection indicating the positive direction of action. Consider carefully whether this direction is actually the one for which you want the force or moment.

If your model is shaded, the shading may hide the arrow. Select the Wireframe, Hidden Line, or No Hidden display option to make the arrow visible.
