Hi Lukas! Welcome to PF!

Show us what you've tried, and where you're stuck, and then we'll know how to help!

I have attached my partial solution to the two pulleys question. I think I have managed to work out the natural frequency, however I don't know what to do more as there are different spring stiffnesses and the pulleys have different radii.

Hi Lukas!

Sorry, but this is too difficult to read.

Can you please type out your work in future?

(btw, there's no torsion in the pulley question)
