Hollow Handlebars vs solid handlebars

[the WaTeRhAwK]

Hogwash, of course.
That issue notwithstanding, those bars are surprisingly easy to bend.
I bent the crap out of mine pancaking a backflip.

ok, mr "know-it-all"...lol how many hogs have you washed....lol


the tensile strength of a hollow tube of aluminum, or ANY other material, IS greater than a tube of the same material in solid form.
reason: because in the hollow form, it doesn't have material through the center helping it separate the opposing side of the bar when pressure is applied. as pressure is applied to a hollow bar, the force is transferred to the sides as a "structural" brace, rather than focused through the middle.


here ya go mr. hogwash...lmao....

regardless of your science, these have proven to retain their shape even when tossed on the beach out here on the west coast. Kid tested crabkracker approved!!!

I'm not saying that they're not nice bars, or don't make nice handlebars. my point is that if superjet-113 is snapping hollows like he's stated, and I'm quite sure he is, he will bend the crap out of those bars, just like matt just stated he did. for some who doesn't get as crazy on a ski, they would probably work fine.

sorry you are just wrong on this one:sleeping:

I run solid bars of the same type and have to agree they are much stronger than any hollows I have tried.

yeah, if you use a different composition of metal of a stronger tensile strength, maybe. if you're talking the difference between plain aluminum up to T-6, or even titanium, comparatively.

out of any two sets of bars, one hollow and one solid, made form the same composition of metal, the hollow bars will have a higher stress value and shear strength, period.

Moved out of the sales thread.

Exactly what is your qualification in discussing these mechanical engineering issues?

If you had actually read any of the stuff you linked, you'd realize I'm right.
Posting links you don't understand doesn't make you an expert on any given subject, Travis.
Stick to music store inventories.

"For a shaft carrying primarily torsion loads, it is the outer elements (greatest radii) that carry the highest stress, so the center core elements contribute little to the function of the shaft. Might as well get rid of the core, make it tubular, and enjoy a better strength-to-weight ratio."


yep... hogwash....lol



stick to staying in school, and take some of your own advice..LOL

 

[Matt_E]

A "better strength-to-weight ratio" doesn't mean better strength. It means that you can save weight while giving up little strength. This implies that the solid core will be stronger (but heavier).

I realize this is a bit harder than saxophone case handles, but try to understand.
If you insist on arguing (why do I think that?), please show me, in your links, how a solid core is actually weaker. (Not "less strength-to-weight")

From your link:

The tensile strength of the shaft (due to helicopter weight?) is simply the cross sectional area of the section multiplied by the tensile strength of the material.

Assuming identical material for hollow vs. solid and the same diameter, it follows that the solid core, having more cross-sectional area than the hollow core, has higher tensile strength.
Not that we're talking about tensile strength here.
I am sure you knew that.

Not another one of these :banghead: Lets atleast keep it simple, i dont want to be confused reading this one.


Whatever happened to the indoor wave pool anyway?

Whoa. Mr. Waterhawk, I don't think you completely understand the term "torsional." On second thought you might want to re-read "tensile" as well lol.

hogwash..lol

I just wante to say (Since the other thread is locked now)
I pulled the pump out of my sj, removed the prop and it fell on the floor and I lost it.

Should I call Impro's to discuss getting a good deal and free shipping on a replacement? After all they are only 250.00

That was a funny thread you guys killed that guy. Poor dude.

If I known the guy needed a jetworks valve I would of stolen one off Penguins ski last weekend and mailed it to him.

 

[CoreyLKN]

It got extracted.

Along with the mice? :biggrin:

That could be argued so easy if you factor in Heat treating and stress relieving, material grade, Cast or forging, Cold rolled...ect ect.

But it looks like you guys are comparing a orange to an apple.
