Discussion Overview

The discussion revolves around a revision question related to a calculation involving two cylinders, specifically aiming to determine a force value of 112 kN. Participants are exploring the method to arrive at this answer, focusing on the necessary information and calculations involved.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant, James, states that he knows the answer is 112 kN but is unsure of the method to reach that conclusion.
  • Another participant suggests that information on the areas of the cylinders is necessary for the calculation.
  • A third participant comments on the lengths provided in the question, noting they seem irrelevant aside from considerations of buckling.
  • A different participant calculates a ratio of the areas of the two cylinders as 7/16 and questions if this is correct.
  • There is a request for James to share his attempts at solving the problem to identify any potential errors.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the method to solve the problem, and multiple viewpoints regarding the relevance of the provided information remain. The discussion is unresolved.

Contextual Notes

The discussion lacks specific details about the areas of the cylinders, which may be critical for the calculations. There is also uncertainty regarding the significance of the lengths mentioned in the question.

Attached is a question from my book, I know that the answer is 112KN but can't work out the method for getting there. Hope you can help, James

You need to have some sort of information on the areas.
 
Which is funny because he has lengths which aside from buckling don't seem to serve any purpose.
 
You didn't give the areas, but by my calculations, it looks like the ratio of the areas of the two cylinders is 7/16. Is that right?

Let's see what you've tried so far and maybe we can spot your error.
