+This model shows how to enable the built-in moment arm evaluation studies.
+The studies can be enabled by setting the switch: `#define EVALUATE_MOMENT_ARMS 1`
+
+The studies will appear in the `HumanModel.EvaluateMomentArms`
+folder.

+The figure shows the moment arms (in meters) for Iliacus and GluteusMaximus inferior) during the hip flexion.
+Agonists muscles (Iliacus) have positive moment arms, and anatagonist (GluetusMaximus) have negative moment arms.

+This  will include a lot of studies (one per DOF) so they will
+affect performance when loading and switching between tabs/operations.
