Hi, I have recently started to analyzed my system's behavior in dynamic motions. i have selected the Servo motor actuator. i have add servo motor for motions.

In the selecting the results option, i have selected the Magnitude force, in definition section it ask me to select Transnational motor object to create the result. I can not understands what i have to select.

The other problem is the system doesn't move with servo motor while the motion is analyzed  with other kind of motor. I don't know what's wrong.
