What is the maximum load on square tubing?

  1. Apr 14, 2008 #1
    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.
