I'm trying to hinge a modified torus to a hole made to a modified cube.

Torus: physics: rigid body | dynamic ON | Collisions shape: Mesh

Cube: physics: rigid body | dynamic OFF | Collisions shape: Mesh

But during simulation the torus simply flies off, instead of hanging. [Model screenshot attached] [enter image description here]1

Blender version: 2.73a

Your described set up works fine.

The dynamic chain element enter image description here

The static collision object enter image description here

Start trouble-shooting

  • Double check your settings.
  • Create a duplicate of your file and delete everything except the problem area.
  • Create the scene from scratch and append it to your file.

  • $\begingroup$ Earlier, I made the objects small (few cm). May be that's why it failed. $\endgroup$

  • $\begingroup$ I changed the sensitivity margin under Rigid Body Collisions to an appropriate small value. Now it is working. $\endgroup$
