Same forces on them. The solid weight 1674g and got a max stress of 7070psi. The hollow (.250`` wall) weight 732g.and got a max stress of 11000psi. So no debate, the solid is stronger, the simulation is 100% accurate. The fun part is lets check how big the hollow have to be, to be as strong as the solid and how i twill weight. That is engineering, that is the fun part. I played with some config for about 5 min and here is the results : With a hollow tube of 2.4`` Dia, you got the same strengh with 900g weight!!! That’s why we say solid is always stronger for the same shape and size, but hollow have a better weight to strengh ratio. I hope i twill clear any doubts about this subject. Theory must match real life and i gave you the example. Short story: It take a 2.4`` hollow tube with .250 wall ( 900gr) to be as strong as a solid 2`` tube. (1675gr) jt just got OWNED.....again.....for da 100th time Quote Link to comment Share on other sites More sharing options...

ZillaFreak Posted November 5, 2017 Report Share Posted November 5, 2017 So which is stronger, 40mm axle that is solid or a 40mm axle that is drilled? You still haven't answer this simple question. Quote Link to comment Share on other sites More sharing options...
ClaudeMachining Posted November 5, 2017 Report Share Posted November 5, 2017 I have a new idea of a thread. It will be called : Ask the dumb engineerI will answer some questions that i found interesting. If my english was better i would do it in vidéo format which can be funny with my french accent.I already got my first subject: Safety Factor.Envoyé de mon SM-G935W8 en utilisant Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted November 6, 2017 Report Share Posted November 6, 2017 I just prefer it to come with a hole so I can put my D**K in it. 4 Quote Link to comment Share on other sites More sharing options...

pp13bnos Posted November 6, 2017 Report Share Posted November 6, 2017 I saw that zilla was talking about a 38" JJ styled drilled axle in the chatbox earlier this morning. Does anyone make a 38" solid or drilled aluminum axle? Can't seem to find any info on a 38. I'm using a Dura Blue +2 right now, and like the idea of loosing a bunch of rotating mass, but like the wider stance. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted November 6, 2017 Report Share Posted November 6, 2017 If you run a 34” play axle with a 9” wheel with 3/6 offset, you should be able to get close to the width you want. Quote Link to comment Share on other sites More sharing options...

Insert other media What will it be?? 46'' ?? My front will have about 48", about 46'' rear should be good. Quote Link to comment Share on other sites More sharing options...
tfaith08 Posted November 6, 2017 Report Share Posted November 6, 2017 Honestly just seems like everyone agrees on the facts but nobody agrees that anyone is saying the same thing.Regarding formulas and engineering...A dumb engineer doesn't make engineering dumb. If the math is wrong, either the physics weren't applied correctly or the physics are wrong. It is almost 100% of the time the former.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted November 6, 2017 Report Share Posted November 6, 2017 If i have time today, i'm going measure my gforce (currently Tusk is making them) then compare to what Loco said. Quote Link to comment Share on other sites More sharing options...

With an 11” wide tire that’ll make it about 48” tire to tire. Quote Link to comment Share on other sites More sharing options...
