I am using the Slotted Hub Joint Calculator. The material that I need for joint is not in the list. The first three columns are all labeled sigma (AL). When I hover over them, they all three say "Allowable pressure".
I take this is probably the ultimate tensile, yield and shear stress, but can someone confirm this?
The column headings should have the correct headings.
I went to the "Help" and it did not even mention the columns.
Thanks,
Kirk
