dislect: 69 GPa is not 69e6 Pa. Try again. (By the way, do not worry too much yet about analyzing the pipes. First, get the preliminary things computed correctly.)

nvn said:dislect: In your M_table equation, I now noticed, you forgot to square the 2 in your denominator. Try again.
Your A3 formula change to -2*t2 is correct. Your answer for x is correct. Excellent work.
Therefore, this is telling you, any x > 7.7 mm is, so far, OK for your current pipes. Therefore, choose the pipe size and pipe spacing you prefer. And you can check Rty3 again. And then you will obtain your P3 value. Therefore, post all of this, and then I will get back with you within one day, to address your other question in post 32.

nvn said:dislect: What is the material of your pipes?
nvn said:dislect: What is the heat treatment condition (also sometimes called temper) of your Al 1060 pipes? And do you already have the tensile modulus of elasticity (E2), tensile ultimate strength (Stu2), and tensile yield strength (Sty2) of this alloy, in MPa? Do you have a material specification name or number?
What is your table top aluminum alloy and temper?
