I didnt know bars were subject to torsion action. what brand?
That's a new concept to me as well. Must be some real twisters out there.

I get it, thats what holds the pole up. No need for a pole spring. Cool.

If you break your bars, just call UMI and tell them and maybe they will cut you a deal and pay for shipping to get you a new set. I could be wrong.

strong comeback. or not.
i do however have a lot of experience with the concepts being discussed in this thread, unlike you Waterchestnut.

I have done tensil strength testing ( as well as rockwell testing) and I can't think of how that relates to handlears. We aren't trying to stretch them. Tensil testing is done with a blank of material that is a specified size and shape (not a tube or bar). It tests the amount of elongation before failure of the MATERIAL. It has nothing to do with shapes. Now if you compare bending a tube and a bar, you need to considder that if the two are made from the SAME amount of material the tube will be more rigid. If the bar is the same diameter as the tube, it will have more material which will make it stronger.
Solid handlebars would be a waste of material, to me. I'd prefer to use a stainless tube, if I were bending aluminum tube bars.

When something is bent (lets say downward), all material above the neutral axis is in tension (ie tensile strength) and all material below it is in compression. The closer to the neutral axis the material is the less of a load it has to deal with until, theoretically, the actual neutral axis itself doesn't have any load at all. This is the concept that leads to tubing as apposed to bars in just about any type of construction.
Watersquawk:
When engineers that have been professionally trained in this type of thing line up to tell you you're wrong, you probably are. As Matt said, it's the whole strength to weight thing you are missing which makes your hollow vs solid comparison apples to oranges. And for the record, the way a handlebar fails has nothing to do with torsion or shear.

Someone mentioned carbon fibre handlebars the other day as now being available for Moto, why not give them a try. The only ones I found were aluminum tubing with a carbon wrap by karbona. http://motorcycle.karbonamotor.com/detail/196710/196710.html
Everything else i found were for mountain biking applications but I'm sure you guys can hammer out this topic for a few hundred pages as well.

only reason we went this route in the first place is they are cheap, got tired of bending the umi bars, and had to find some way to get travis on the other side of a debate...WDK has some stronger alloy bars but too much and hard to locate in bulk. http://waterdawgkustomz.com/proddetail.php?prod=SR8HDLBAR1&cat=5

McMaster stells that bar stock. It's only like $40 or so for 8 feet of it.
Can't matt & waterhawk just argue this one out over the phone? :thinking:

No way to talk on the phone. Travis needs one hand on the keyboard, and the other hand on his you know what- at all times.
so they do but too much...

Waterdawg:
Handle bar measures 24" wide, 7/8" dia., 0.120 wall, 2024 T3 alloy tube. Much stronger than 6061, don't mess around. Features CNC machined radiuses on each end and smooth finish.
Price: $50.00
mcmaster:
Material
High-Strength Aluminum (Alloy 2024)
Wall Thickness
.120"
Length
6'
Outside Diameter
7/8"
So, for $81 from mcmaster, you get enough tube to make 3 handlebars, so $27/each instead of $50/each from Waterdawg. Smooth the ends a little and you're done, then sell the other 2.

and I thought it was for hot water plumbing all this time...
