I am a little confused how it is possible to set a Force/Effort on a Joint that has no Mass or Inertia. I try to understand what is happening when calling the SetForce() function as described in the API(see link below ).

I tried to find the source code for the SetForce method. I looked here: but setForce() is just in the .hh not the .cc.

Does someone know more about that topic and can help understanding? Thanks !

The joint connects two links and those links do have mass, isn't that right?

Thanks for your answer. That is right I guess. So it sets the force at the links not the joint...
