It seems so simple, But what do I know?

    Not much. Im not sure where to put this so mods move it as need

    Anyways here is the back story,
    We have been building this roll bar out of 1" square tubing but we need to gain 2" overall width without changing much. the first thing I could think to do is add 2" overall length of the tubing and add the 2" into the B measurement and that maybe made it half inch bigger, We have tried lots of other things and none seem to work.

    So I am turning to the internet for help.

    Thank you for your time.

    PS the angles are pre-set into the bender

    Hey justin_jkj and welcome to the forums.

    I'm not sure what you are trying to do: are you trying to get the biggest area given some length of tube? (The area being the area enclosed within all four sides A,B,C,D and the horizontal line).

    Are you trying to get the biggest area with a length of tube and fixed angles for your piece of equipment? (The machinery that shapes the tube according to the preset angles?)

    Im trying to spread side A and side D apart by 2".

    but adding 2" to the overall length and then into the B measurement did not work at all.

    If B is parallel to the line at the bottom and the angles stay the same, I can't see why this wouldn't work.

    Can you describe what went wrong when you tried this?
