Verify 2 Node Frequency with Holzer's Method

[hanson]

Hi!
How to use Holzer's method to verify that a given natural frequency of a torsional vibration system should have 2 node?

Is that when I construct the table and do the iteration, I will finally find that there are 2 sign changes of the "theta"? Therefore, we can conlcude that?

Could you elaborate on the system please.

If I am correct, a shaft with N discs would have N-1 nodes.
