Jake,
You don't hear me say this often, but :
If you are too $%#%@ lazy to even read the post then your comments are completely void of any meaning. They are are truly baseless.
And cut the BS about "efficiency". It took me 30 minutes to develop and implement the mathematical model producing the equivalency results. Even at a going rate of 100 buck per hour, this excersize would have been well worth the time of any professional engineer as the price difference between alu and carbon tubes is much bigger then that. THAT, my friend, is true "efficiency". And also what engineers are supposed to do, thats what they are trained for. To find solutions to design problems that satisfy the criteria and be as inexpensive as possible.
I don't know exactly how to intepretate this quote :
... create a tube of the same weight out of aluminum with the same bending characteristics as one from carbon. Well no $hit Sherlock!
If you agree that this can be done, then you have just confirmed all my points.
If you disagree then, well, you have just proved to be one of those engineers that prefers gut feelings over true science. A dressed up monkey pretending to be an educated man. We already have far too many of those in our societies today. Please assure me that you are not one of those, I would consider that a loss.
I like you personally Jake, so take this post as a single issue disagreement, even though it is a very fundamental one.
I simply can't stand dumb people thinking that they have anything meaningful to say without having put in the effort to understand what is being discussed.
