  • Page ID
  • The inertia matrix or inertia tensor is \[\left[I_{xx} -I_{xy} -I_{xz}\-I_{yx} I_{yy} -I_{yz} -I_{zx} -I_{zy} I_{zz}\right]\] In linear algebra it was shown that for some angle equation 55 can be transform into \[other matrix\] System which creates equation 56 referred as principle system.
