    Simple really. You don't even need to know the diameter of the earth:

    If
    D= diameter of the earth at any particular point
    X= additional length of string
    π= Pi

    (D + 2")π - Dπ = X

    (D + 2")π/π - Dπ/π = X/π

    D + 2" - D = X/π

    2" = X/π

    (2")π = X = 6.2831853 inches = 0.523598775 ft = 0.000099166 miles

    =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    BTOS was Burroughs Operating System Twenty, a command line operating system that unlike DOS's blank screen started with a menu of available tasks. It also assigned a lot more memory to the keyboard buffer, so if you were on a slow computer and knew what you were doing you could input the data that a program required before the screens updated by quite a bit, and then go get a cup of coffee or something while the computer caught up.
    Of course that was back in the early 90's when the light wheel vehicle maintenance unit I was probably in was taking care of the stuff coming back from Desert Storm. And we were using computers that were top of the line for the mid 80's for maintenance management. I guess if they were properly stowed on a standard Air Force pallet, the computers could apparently be dropped by parachute out of the back of a plane and land safely though.
    I never had the guts to jump out of a perfectly good aircraft, but I admire those who do.

    This looks right and I remember doing a puzzle like this in school, yet when I use numbers I get to something way different :S wtf am I doing wrong here

    using mean radius of earth at 6371km
    radius of string 25mm above earth at 6371.000025km

    C1 = 2 * pi * 6371km
    C2 = 2 * pi * 6371.000025km

    C1 - C2 ~= 1.57 *10^-4 = 0.000157mm

    My intuition tells me 78.5mm but my numbers tell me 0.0001mm. What's going on here?

    km not mm.
    I got 0.157 meters using your values.

    Re: The random thought thread

    The solution to the quandary :
    (D-d) x pi = 6.28(units)

    How does the ball and the string quandary translate for a Tech (Junior Techs)?
    If you invert the quandary we have a Big "D.iameter" going down to small "d.iameter".

    Big deal you might say, who gives a sh!t...!

    Translating the diameters to that of rollers or cylinders:
    A rubber feed roller(s) have warn down 1mm in radius from "D.iameter" down to "d.iameter". That translates to a lost of 6 units(mm) of paper feed in.

    A rego-roller(s) have worn 0.5mm radius in the middle of the roller.
    The problem equates to 3mm of registration feed lost. (a PM task)

    An ITB , fuser idler roller, or belt tensioner roller has lost(squashed) 1mm in radius. There is 6mm/2 belt slipping or falling loose belt. (Problem: Torn belts.)

    In keeping with the cylinder ratio :
    An unwanted periodic pattern appears on a print out, what is the length of the periodic pattern in relation to the cylinder that caused the problem ? How can we quickly find out if the unwanted pattern is coming from a drum, dev,rego roller etc..?

    Given: We know the unwanted pattern on the print out is periodic.
    Using the print out, we make a quick mark using a pen at the offending period marks on the print out. We can then roll the print out paper into a cylinder until the pen marks align. The alignment will leave the diameter of the offending roller or cylinder. Alternatively we could measure the distance between the pen marks and div by ratio Pi to arrive at the offending diameter.

    Senior Techs know the above as pedantry, Junior Techs struggle with the basics.

    Junior Techs have the opportunity grasp the concept of D.iameter worn d.iameter, or (D-d)pi, and how that translates to copier/printer problems.

    When all the quandary b/s is removed you have (D-d)pi.

    Re: The random thought thread

    The teacher gave her fifth grade class an assignment: Get their parents to tell them a story with a moral at the end of it.

    ---The next day, the kids came back and, one by one, began to tell their stories.

    There were all the regular types of stuff: Spilled milk and pennies saved. But then the teacher realized, that only Janie was left.

    "Janie, do you have a story to share?"

    "Yes ma'am. My daddy told me a story about my Mommy. She was a Marine pilot in Desert Storm, and her plane got hit. She had to bail out over enemy territory, and all she had was a flask of whiskey, a pistol, and a survival knife.

    She drank the whiskey on the way down so the bottle wouldn't break, and then she parachuted right into the middle of 20 Iraqi troops........

    She shot 15 of them with the pistol, until she ran out of bullets, killed four more with the knife, till the blade broke, and then she killed the last Iraqi with her bare hands."

    ''Good Heavens, 'said the horrified teacher. What did your Daddy tell you was the moral to this horrible story'?"

    ...."Don't Screw with Mommy when she's been drinking."
