(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I've been given this as a piece of coursework and I'm having a bit of trouble starting it. I know most of what I need to do once I can figure out how to calculate a few basic (though essential) values.

The first part to the question is as follows:

"Determine, using matrix methods involving the Dynamic Characteristic Matrix Equation {DM}, and hand calculations, the natural frequencies of torsional vibration ignoring the effect of IC (coupling) mass inertia effects for the model indicated in figure 2 but including all stiffness elements."

2. Relevant equations

None supplied in this coursework however here are the relavent formulae for this section of the module I am studying:

3. The attempt at a solution

I'm not entirely sure how to enter equations on this forums so ive just provided a print screen of my working so far...

Any help would be greatly appreciated. I Imagine the answer is fairly obvious however vibration theory has always been one of my weak points!

Cheers, DFC
