Stress forces on aluminum tubings

In summary, the discussion is about comparing the strength of two types of aluminum tubing for a project. The round tube with a 2 inch outer diameter and 0.083 wall thickness seems to be stronger than the square tube with a 1.25 inch outer diameter and 1.125 wall thickness. The main concern is which tube is better for withstanding various stress forces for a 60 inch length.

Hi,

Please forgive me if this post is in the wrong section. I'm interested in working on a project but my physics is very rusty in terms of calculating stress and in need of help. I would like to know which is better given the below aluminum 6061-T6 tubing with similar weights to withstand all stress forces axial, radial/torsional, sheer, tear, bend, etc... for an approximate tube length of about 60 inches:

2 inch outer diameter round tube with 0.083 wall thickness - cross sectional area of 0.500

versus

1.25 in outer square tube with 1.125 wall thickness - cross sectional area of 0.563

Thanks for your help.

mibiz1: Globally, the round tube listed in post 1 currently appears to be significantly stronger than the square tube listed in post 1.
 

1. What causes stress forces on aluminum tubings?

Stress forces on aluminum tubings can be caused by a variety of factors, including external forces such as weight, pressure, and temperature changes, as well as internal forces such as residual stresses from manufacturing processes.

2. How do stress forces affect the durability of aluminum tubings?

Excessive stress forces can cause deformation or failure of aluminum tubings, leading to decreased durability and potential safety hazards. However, controlled stress forces within the material's limits can actually improve its strength and durability.

3. Can stress forces on aluminum tubings be predicted?

Yes, stress forces on aluminum tubings can be predicted using mathematical models and simulations. These tools take into account various factors such as material properties, external forces, and geometry to accurately predict the amount and direction of stress forces on the tubing.

4. What are some methods for reducing stress forces on aluminum tubings?

One way to reduce stress forces on aluminum tubings is by using thicker and stronger materials. Another method is to design the tubing with smoother curves and angles to distribute stress forces more evenly. Additionally, proper installation and maintenance can also help minimize stress forces on the tubing.

5. Are there any safety precautions for handling aluminum tubings under stress forces?

Yes, it is important to always follow the manufacturer's guidelines for handling and installing aluminum tubings under stress forces. Additionally, wearing proper personal protective equipment and ensuring the tubing is properly supported and secured can help prevent accidents and injuries.
