Rotational Inertia

  1. Oct 27, 2005 #1
    How would I prove that the Rotational Inertia of a unform sphere is 2/5M(R)squared, about any axis?:confused:I have no idea where to start. . .

    how did you findratational inertia of others?
    reply to this first


    i think you migh be knowing the method to find sphere volume. similarly consider sphere as a overlapping of inginite cylinders.
