Trifilar suspension/pendulum

  1. trifilar suspension/pendulum is used to determine the moment of inertia(MOI) of an irregular body. In order to determine MOI, we need to place the given body whose c.g. has to pass through the c.g. of the platform of the suspension/pendulum.

    my question is how do i determine the c.g. of a given irregular body?
    can we determine the MOI of the given body by placing it at other place where it's c.g. doesn't pass through the c.g. of the platform?
