Hi, I hope someone can help, I'm trying to design a trailer which uses adjustable legs on each corner as support legs while it is is use.(adsbygoogle = window.adsbygoogle || []).push({});

The legs are adjustable and have drilled holes for the position pins, and I am trying to work out what wall thickness of leg will be adequate to provide enough strength. The outside dimension of the leg is fixed, as is the pin diameter, only the wall thickness and hole spacings can be varied (see attached image).

I'm looking for a calculation on the stress, or assistance on how to work this out please? I'm sure there is an easy answer but I'm struggling...

The legs are 38mm (1 1/2") square/box section (hollow) 316SS if that is of any help... and the holes are 16mm diameter..
