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"
