The tale of the tape

26 and a quarter
 
Actual....26.021 feet

Calculator...27.0417 feet. ==>3.9% over actual

Moi...25.92 feet. ==> .4% under actual.

Like I said...Scooter402 FTMFW. :beer:




Aight...gonna go back in my corner and eat paste again. :lol:
 
Just a fyi.....
The calculator comes out with the same answer as @Scooter402 when 12.75 is used as the diameter. I am surprised it's that accurate .....

You are a smart dude......
 
I know there's already been a couple of correct responses to this...one of them cheating, but it's still a win. Let's see how a scientist would approach the problem...

This can obviously be approximated very closely to a spiral. After all, past the first couple wraps, it is a spiral. Attached is a derivation of a formula for arc length, since you specified to show work...

The first formula is a general formula for a spiral, where you begin with a constant (tube diameter) with a factor that increases the radius incrementally with a change in angle rotating about the origin -

r=a+b(theta).

The integral above for arc length comes from the integral for the length of a line.

Take that oompa loompa crap back to the Chocolate Factory playground. :eek:

Fuck you smart engineers :flipoff2:
 
Define "official engineer" :lol:

There is a chain tire store around here that has recently changed it's name to "Tire Engineers" or something like that. I'm sure everyone there is an official engineer in their own mind.
I had quite a conversation with an engineer from NY city. He said he was an engineer for some tower in ny. I was asking him how long a project like that took, when the expected completion date, does he have other projects inline, etc. His answers didn't really add up. He said it was a full time job, the building was complete, and he was happy there and not looking for other work. After about 10 minutes of me prying, thinking he was full of :poop:, I realized he was a supa. It sounded much cooler to say you were a building engineer for soandso tower in nyc.
 
I don't think anyone who solved it is an official engineer.
:eek:
We don't need them anyways.
Damn, you caught me again! :D

Yep...he called my bluff. Right now I'm an industrial babysitter (manager). I'm waiting for a replacement for my replacement (the supervisor that works for me will take my chair, gotta find someone for his now), then I can go assume my post here in my current company as a mechanical design engineer.

But by education, I have a B.S. in Physics...you have no idea how many times I've been asked by ENGINEERS how that would apply to the job...then I explain the curriculum, and they say "wow, that actually sounds a lot like my M.E./E.E. degree." I typically respond with "No, actually your degree sounds a lot like a Physics degree...you DO realize that engineering is applied Physics, right?"

I usually get the crooked stare o_O, followed by "Well, uh...I mean...I guess so..."

Me: :shaking:

Okay, off my soap box now. I'll resume my post in the corner. I'm almost out of paste though...anyone got a refill? :lol:
