# Engineering Questions Help - Lukas

• Lukas Pohnan
In summary, Lukas is seeking help with completing a question involving two pulleys, different spring stiffnesses, and varying radii. He has provided a partial solution and believes he has calculated the natural frequency, but is unsure of what to do next. Another user has asked for a typed version of his work and clarified that there is no torsion involved in the question.

What have you tried?

Welcome to PF!

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.

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

Here is my answer to the 2 pulleys question in word.
