Todays quick lesson Square vs Round

[xDUMPTRUCKx]

You seem to be talking a lot of smack on a lot of people, on a lot of forums, dumptruck. You should probably lay off of that while some people still like you.

Aww come on man. A lot of people? Please.

First off I wouldn't classify my poem as "talking smack" more of a retarded attempt at being funny.

Who have I talked smack about lets see....

Ashman and vintage.

They got what was coming to them and it was all return fire.


I've met phil a few times and been out wheelin with him why would I talk smack on him?

People who know me know I'm just an asshat who like to goof around. When it comes down to it, of the people I've met in person and talk with on occasion I'm sure there's not many who like I would talk shit on.

I infact try and help out as many people as I can, driving unheard of distance with only the intent to help others no matter the cost to me. I'm sure someone will vouch for me here.


You should probably get to know me before you take a shot at me like that.

"You should probably lay off that (talking smack) while some people still like you"

That could be taken as offensive to some.

Pm me if you wanna talk.

You got the retarded part right.

I wouldn't know anything about doing that. I havent driven a hundred miles out of my way to railroad someone some parts in at least oh .. 3 days. It's been at least two months since I've lifted someones jeep for them, but I have two scheduled in Jan. Lets not get into who does what to help who at what cost, it isn't really the point there.

You should probably get to know me before you take a shot at me like that.

There was no shot at you there. Your humor as you called it a post up is not very funny, but portrays you as an ass. I was meerly offering some mildly indifferent advice that you be more carefull about that. I've met you twice, you seemed pretty nice both times, several of our mutual friends don't have much in the way of negative things to say about you - but that doesnt change the way your posts have been reading lately.

I'm not really sure how, but your welcome to take offense to it if you'd like. It's not a complete day if I don't piss *somebody* off.

I don't know about you but when someone says I'm going around talking smack on all sorts of boards like I'm running around with a hatchet ruining peoples lives its pretty uncalled for.

It was supposed to sound retarded. I am an ass, that's pretty well known by now. You don't think its funny but mabey some other tard like myself might.

I think you sound like an ass coming out here being a prick to me when I've done no harm to you. This is why there are private messages no? But you had to post it up in the middle of someones technical conversation and why?

Usually from what I've seen people post completely retarded or irrelevant comments in hopes to get the thread back on track. That was my intention, oh and I have a passion for the art of japanese poetry......


Mabey I'm just agitated now but I just don't see it. You say your trying to help by attempting to make me look like someone who ruins threads with smack talk all day on all the offroad forums I can.

I don't really think I talk much smack on this board, and for you to say that to me I just don't see the point.

As for pirate, its the internet. Who cares. Pirate is full of constant badgering and slanderous talk and I don't consider it my home at all so why should I care, or you for that matter, what I say or do on those boards.

I might have taken you seriously if you would have pmd me that instead.

It gave me a good laugh. Random shit, its funny.

Don't mispell bearing either.

Each tube has it place. Each one has it +s and it's -s.
For control arms/slider and alike. Were the direction of stress or inpack is mostly in one demesnial. Square tube will win hands down pound for pound.
R-tubing will take a longatudegenal twist or much better when this is needed.
Each tube has it''s place.

Are you and KRAWL the same? If not, my question was directed at him. If so, why the need for a new name? :doh:

nope im not krawl. sorry to disapoint...lol
just joining in on the fun

That was a little lame.
Why do you need a front 60?

Well I did follow the 5 7 5 format.


I need a front 60 cause its cheaper than breaking stuff.

I wanna run the fun stuff. Cause I live close enough to jv I should build accordingly.

I go with a 44 and ill brake 2 out of every 3 trips out on 37s. I want 40s or 42s. Replacing parts on my 44 will cost the same as an entire 60. Ill proably spend the same amount anyway.

Do it right or don't do it at all.


I'm gonna run big bear on 40s you just wait and see.

blah, blah, blah...

Besides the simple fact that there is more material in square vs round, sure... square tube of the same size and wall is stronger than round. but, pound for pound, I'm kinda curious.
so maybe do the math again with like weight tubing.
2"x.120 is 2.409 lbs per foot
square tube in the same weight range would be
2"x2"x.095 is about 2.461

I'm working on learning the math. Sis in Law is a structural engineer so she made me a work sheet. just waiting for her to send me the formula for square and rectangle tube.
so what does the math say Overkill?

I calculated the sectional modulus for 2" square, .25" wall tubing to be .91145 in^3 across the flat and .5601 in^3 across the corners (45 degree rotation), and I also got .53594 in^3 for a 2" dia .25" wall tube.

The sectional modulus for 2" dia .120 wall tubing is .31384 in^3 and the sectional modulus for 2" square tubing .095" wall is .4389 in^3 across the flat and is .25071 in^3 across corners (45 deg rotation). So a square tube is still stronger in bending across the flats than a round tube by 28%, unless you build your junk at a 45 degrees with square tubing then the round is stronger by 20%.

If we dont take the radius of the corners on the square into account (which is significant and should not be overlooked), I come up with the same for the square on the flats, but vastly different for the corner loading...

I come up with 0.644 in^3...

This stems from the basic formula for moment of inertia for a rectangle across the points = ((b^3*h^3)/6(b^2 +h^2)). For a square b = h, so this gives us (h^4)/12, which is the same as on the flats. If moment of inertia is the same, the relationship between the two section moduli should be inversely proportional to the relationship between the distance to the outer edges...

What are we doing differently?

Your right, I didn't account for the corner radii.

I actually used the calculators on engineersedge.com to do the calculation and I know some of them are incorrect (which is why I never use them at work) but it looked in the ball park for the calc across the corners so your answer may be correct. I have my reference material (old text books) at work and I didn't have to work today so I didn't do the hand calc. I follwed the same equation as stated above for across the flats though as I remembered it.

this just went way over my head, but its been good reading!!!!

Winter time is hell! We can't get to the trails for a few days and turn on each other.
I don't know were you duds are coming from, but I was talking about tubing.

Did you catch my post on one of the other forum? Were I mention my "sweet butt" and get all turned on? Well, dud it ant gona happen!

Maybe winter is bad for you but its the best time for me to go wheelin as its usually 50-60 deg out here in the Cali desert, the summer its too hot to go wheelin becase its 120 deg out and the rig overheats going slow in 4wd with the A/C on so that when you stay home and rebuild your rig. I was out yesterday and it was 70 deg out, very nice.

I don't know were you duds are coming from, but I was talking about tubing.

Now I'm A "Dud" and you don't even know me, sound like you need to reread your own complaint above. I'm just trying to help everyone explain the benifits of using square tubing for bending load applications over round tubing.:hang: Have a good winter, I am.
