Can Jack simulate balance if your holding an object and how it affects their center point of gravity. Potential scenarios could be any sort of situation and unique situations like one handed lifts or odd pushes and pulls. Can this be fed into fatigue studies?
The posture prediction in Jack does take into account forces applied to the palmcenter sites of the figure. Apply the object load forces to the palmcenter sites using the Loads and Weights interface. When you manipulate the figure through the Human Control Panel and don't have torso or pelvis body parts locked, the whole body posture prediction will take these loads into account. The computed joint moments are used in the computation of muscle capability, so will be used in the fatigue assessment as well.
