Discussion Overview

The discussion revolves around a homework problem related to the two pulleys problem, focusing on engineering concepts and their application to analyze the system, particularly in determining the natural frequency and addressing the complexities introduced by different spring stiffnesses and pulley radii.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • Lukas expresses difficulty in completing the homework questions related to the two pulleys problem and seeks assistance.
  • Participants encourage Lukas to share his attempts and specify where he is stuck to facilitate better guidance.
  • Lukas mentions he has calculated the natural frequency but is uncertain about the next steps due to varying spring stiffnesses and pulley radii.
  • One participant requests that Lukas types out his work for clarity, noting that the provided solution is difficult to read and mentions that torsion is not relevant to the problem.

Areas of Agreement / Disagreement

The discussion does not present any consensus, as participants are focused on clarifying the problem and assisting Lukas without resolving the complexities of the two pulleys problem.

Welcome to PF!

Hi Lukas! Welcome to PF! :wink:

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