3 branches discussed previously. However, as on the latter, the translation and rotation
movements are coupled. This is all the more true since the length of the pen can be
relatively significant when the user carries out a rotation movement around its axis
(due to the screw, this movement takes place by an extension of the pen). This extension
also has an effect on the force capacity in rotation.
