I tried to use this configuration to simulate a sensor that measures the 
force and torque at a particular point. So I broke up my rigid body into 
two separate parts and connected them with a fixed joint. Then I can use 
the joint feedback to get the force/torque. I'm still experimenting with 
this approach and I'm not sure yet if it's really suitable.
What other alternatives are there to simulate such a sensor?
