Hi Lukas! Welcome to PF! :wink:

I have attached my partial solution to the two pulleys question. I think I have managed to work out the natural frequency, however I dont know what to do more as there are different spring stiffnesses and the pulleys have different radii.

Hi Lukas! :smile:

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)
