+:::
+
+The objective of this example is to adjust the eccentricity of the cable wheel
+such that the arm muscles experience a constant effort throughout the elbow
+flexion taking the change of moment arms of the muscles into account.
+
+It is not possible to obtain a completely constant muscle effort with only the
+eccentricity as parameter. However, if more parameters were introduced into an
+actual design optimization, then it is likely that an almost completely uniform
+effort profile could be obtained.
+
+By chaning between the files "EnvironmentOptimized.any" and "Environment.any" it
+is possible to to see the machine with adjusted eccentricity and the one with
+zero eccentricity
