+\end_inset

+\end_layout
+
+\begin_layout Itemize
+\begin_inset Formula $d^{2}$
+\end_inset
+
+ is the square of the distance from the center of the disk to the center

+\end_layout

+\begin_layout Standard
+Finally, you must add the IM of the disk to the IM of the weights.
+\end_layout

+\begin_layout Standard
+\begin_inset Formula $I=I_{d}+n*I_{w}$

+\end_layout

+ This is the value you must enter in the chronojump software.
+\end_layout

+\begin_layout Standard
+\begin_inset Formula $I_{d}$
+\end_inset

+\end_layout

+\begin_layout Standard
+\begin_inset Formula $n$

+Using Chronojump to calculate directly the IM of the disc with some attached
+ weights
+\end_layout
+
+\begin_layout Standard
+Attention, this is not the method recommended by the Chronojump team.
+ As the manual calculation of the IM of the weights is much more accurate
+ we don't recommend to use this method.
+\end_layout
+
+\begin_layout Standard
+This method can be useful if you don't want to make the manual calculus,
+ or if you want to check your calculus.
+\end_layout
+
+\begin_layout Standard
+You can calculate the IM of your configuration adding an extra weight that
+ unbalance the disk.
+ As the normal use of the inertial machines requires a balanced configuration
+ of the extra weights you attach to the disk, the center gravity of the
+ disk and the weights should be on the center of the disk.
+ Adding an extra reference weight will unbalance the system and, as in the
+ section 1, you can make oscillate it and measure this oscillation with
+ the encoder to know the IM of the disk and the weights
