ClaudeMachining Posted March 11, 2016 Report Share Posted March 11, 2016 Not for nothing, you use to because the same thickness is lighter. You don't make it the same weight. At that point why use it at all?? Since it have a better G/D ratio, the Ti tube will be lighter. It will not have the same Dia or thinckness but IT WILL BE LIGHTER and as stiff as the chrome one. If you have 'fitting issue' ok. But if you want the lightest, Ti all the way. FFS guys, why do you think Ti is the material of choice in aeronautic??

J-Madd Posted March 11, 2016 Report Share Posted March 11, 2016 I've seen a full Ti drag chassis. I don't know the wall thickness but the tubing diameter looked the same as most chromoly chassis. It flexed so bad that the foot peg would almost hit the ground if you stepped on it. It threw the chain and/or went so violently crooked that it was unsafe to ride.

ClaudeMachining Posted March 11, 2016 Report Share Posted March 11, 2016 Definition from the net: Specific modulus Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. It is also known as the stiffness to weight ratio or specific stiffness. High specific modulus materials find wide application in aerospace applications where minimum structural weight is required. The dimensional analysis yields units of distance squared per time squared. So again, at the same weight, they will bent about the same.

ClaudeMachining Posted March 11, 2016 Report Share Posted March 11, 2016 Titanium alloys : G (young modulus) : 110 to 119GPA D (density) : 4.4 to 4.5mg/m3 G/D (stiffness to weight ratio) 25-26.5 ChroMo Alloys: G: 150-245 D: 7.75 to 9 G/D : 19.35 to 27.2 I rest my case. Dont try to bully your way out JT. You know Shee and machining, fair enough, but we are talking engineering/material here, we are not in the same league.

locogato11283 Posted March 11, 2016 Report Share Posted March 11, 2016 The Ti chassis was way lighter if the tubes were the same. But it won't hold up so the weight is irrelevant. Quote Link to comment Share on other sites More sharing options...
ClaudeMachining Posted March 11, 2016 Report Share Posted March 11, 2016 But it won't hold up so the weight is irrelevant.Then just make it the same weight as the chromo one and it will be as stiff. I posted all the data, i cant say munch more than that. Quote Link to comment Share on other sites More sharing options...

J-Madd Posted March 11, 2016 Report Share Posted March 11, 2016 LOLOLOLOLOLCmon man. Why in the hell would you want to make a Ti chassis the same weight as steel? We could make an aluminum, wooden, fiberglass, bamboo, plastic.... any material and be the same weight as the steel and likely be as strong or stronger. Weight IS the issue here. So you can teach us which is stronger per given weight or cross section or whatever but you lost sight of why we are debating this in the first place.

trickedcarbine Posted March 12, 2016 Author Report Share Posted March 12, 2016 You said in the SB : 'Take 1 inch tube same wall thickness in TI and chrom. Let me know what one flexes more' You just show me that you dont undertand at all. The Ti tube will weight a lot less. Make them the same weight and the Ti tube will flex less. That's what i mean when i say Ti p4p, will flex less than steel. Yes, but that's not very practical. You say weight to weight? How big is a 10 pound cube of Ti vs a 10 pound cube of chromoly? When choosing tubing for a project I'm choosing tubing dimensions not weight, although weight is a factor. So yeah pound for pound stronger. But not always better when comparing material sizes in practical real world applications. Quote Link to comment Share on other sites More sharing options...
