The static fatigue visualizer estimates the amount of time that a given joint could sustain the simulated task-focused behavior, often referred to as an endurance limit. For example, think of holding a soup can in each hand, then extending your arms out beside you into a “T.” The endurance limit is the duration of time that you could last before you had to lower your arms down to rest.  The predicted static fatigue/endurance limit for each joint depends on the torque at each joint, which depends on the forces and posture. Changing the postural requirements or the reaction force requirements will change the static fatigue/endurance limits in the visualizer.
Please note that the static fatigue visualizer is limited to estimating endurance limits for static postures that are maintained for 60 minutes or less.
To interpret the data, users often find it helpful to first find the “weakest link,” or the joint with the lowest endurance limit.  If the simulated task-focused behavior is expected to be held for a duration that is less than the shortest static fatigue/endurance limit, the task could be deemed acceptable (from a static fatigue perspective). If the simulated task-focused behavior is expected to last for a duration that is longer than the shortest static fatigue endurance limit, the task may need to be redesigned (reaction force requirements reduced, or postural requirements altered).
