 We also discuss how the disturbances are implemented in the model.
 
+Centrifugal forces can be viewed as a constant force disturbance in the frame of the nano-hexapod.
+Some numerical analysis of such forces are done [[file:centrifugal_forces.org][here]].

 * Simulation of Experiment ([[./experiments.org][link]])
 Now that the dynamics of the Model have been tuned and the Disturbances have included, we can simulate experiments.
