Hi Guys,
Can someone explain in layman's terms how the safe axial load (SAL) is calculated on steel tube based on its length.
I have a data sheet for Type 4 tube that starts from 200mm and works its way up to 6000mm in 200mm increments. Each length has a SAL in kN. E.g. 200mm = 79.3kN, 400mm=76.5kN, 600mm=70.9kN and so on until you hit 6000mm= 4.3kN.
I'm assuming Euler's formula is used in there somewhere but what am I missing? I've tried using the formula but I cannot seem to get it to correlate to what's on the sheet.
Can any of my learned friends out there assist in explaining how they arrived at those figures.
Cheers
Jason
