What is the maximum load on square tubing?

Click For Summary
SUMMARY

The maximum load on 3.5" x 3.5" x 3/16" square tubing with a 1" adjustable pin hole depends on several factors, including the material type and treatment. The discussion highlights the necessity of identifying whether the tubing is made of mild steel and understanding the loading conditions to accurately predict failure points. Without this critical information, it is impossible to determine the allowable load on the pin before the tubing tears under stress.

PREREQUISITES
  • Understanding of material properties, specifically mild steel.
  • Basic knowledge of load conditions and stress analysis.
  • Familiarity with physics principles related to structural integrity.
  • Experience with engineering calculations for load-bearing structures.
NEXT STEPS
  • Research the mechanical properties of mild steel, including yield strength and tensile strength.
  • Learn about stress analysis techniques for square tubing structures.
  • Explore engineering software tools for load calculations, such as ANSYS or SolidWorks.
  • Study the effects of different loading conditions on structural components.
USEFUL FOR

This discussion is beneficial for structural engineers, mechanical engineers, and anyone involved in designing or analyzing load-bearing structures using square tubing.

Can anyone help to determine the maximum load on 3.5 " x 3.5 " x 3\16 " square tubing with a 1 " adjustable pin hole. This tubing was inside a 4 " x 4 " support . See the attached picture. I need to know the load or force allowable on the 1 " pin prior to the 3.5 " x 3.5 " tearing from the stress. I am not an engineer and lack \ forgot how to use physics to figure this out. Thanks in advance.

Welcome to PF, Tony.
More information is needed. Going by the picture, I would guess that the material is mild steel, but it's important to know for sure not only what it is, but how it was treated.
I'm afraid that I won't be able to help you anyhow, but others will need that information.
 
Danger is correct, this is a very complex problem and you need to know more about what kind of material it is and the loading condition before you can predict the failure.
