Discussion Overview

The discussion revolves around determining the stress in different sections of a tile under load, focusing on the tension values for each section. Participants explore their calculations and reasoning related to the problem, which appears to involve principles of statics.

Discussion Character

  • Debate/contested, Technical explanation

Main Points Raised

  • One participant expresses confidence in their solution but acknowledges uncertainty due to differing results from teammates.
  • Another participant agrees with the tension values calculated for the three sections, indicating a shared understanding of the diagram presented.
  • A participant highlights a disagreement with teammates who calculated the tension in the middle section as 8kN, arguing that this would lead to structural failure of the system.
  • A later reply suggests that the teammates need to review concepts in Statics, implying a potential misunderstanding of the principles involved.

Areas of Agreement / Disagreement

There is some agreement on the tension values among certain participants, but disagreement exists regarding the calculations made by teammates, leading to uncertainty about the correct approach.

Contextual Notes

Participants reference specific tension values and calculations, but the discussion does not clarify the assumptions or definitions used in their reasoning, leaving some steps unresolved.

Homework Statement
There is a bar embedded in a tile, which consists of three sections and the following loads are applied to it. Determine the stress in each section.
Relevant Equations
A = pi(r)^2/4; E = F/A
For this problem the teacher explains the procedure for made it. I am sure that I am fine with my solution, but hours ago many teammate thay had different results...and now I am not sure.

If I understand your diagram correctly, I agree with the tension values that you determined for each of the 3 sections.

Thank you very much for confirme it. Teammates they only took the (4kN +4 kN) = 8kN for the middle section, I simply said: "if they take 8kN, the force of the section below will cause the system to simply fall"

Your friends need to review Statics.
