Inertia matrix

  1. Nov 24, 2012 #1
    hi everyone! i'm very confused about inertia matrix... i searched all over the web but didn't find a concise explanation of why it is useful to use it.
    What's used for ? When should i use it ? the wikipedia explanation is too formal and it's difficult for me to understand... so can somebody give me an effective explanation on what is, how does it function and when i should use it ?

    The mass moment of inertia matrix is used in the analysis of the dynamics of a rigid body. These bodies commonly include aircraft, spacecraft, and marine craft.
