 *** Introduction
 
-Three main resonances are foreseen to be problematic for the control of the APA300ML:
-- Mode in X-bending at 189Hz (Figure [[fig:mode_bending_x]])
-- Mode in Y-bending at 285Hz (Figure [[fig:mode_bending_y]])
-- Mode in Z-torsion at 400Hz (Figure [[fig:mode_torsion_z]])

 These resonances correspond to parasitic resonances of the APA itself.
-They are very close to what was estimated using the FEM:
-- X-bending mode at around 190Hz (Figure [[fig:mode_bending_x_bis]])

-- Z-torsion mode at around 400Hz (Figure [[fig:mode_torsion_z_bis]])

 The resonances are indeed due to limited stiffness of the APA.
