Homework Help: Pythagoras theorem - Shaft alignment TIR

  1. Jan 14, 2010 #1
    1. The problem statement, all variables and given/known data
    I am going the do some alignment of a shaft.I use a dial indicator for measurement, and use rim-face techniques. Then I need do calculate the total TIR (Total Indicated Runout).

    Here is my result of my measurement (Dial indicator).

    Top: 0
    Right: +0,08
    Bottom: -0,27
    Left: -0,35

    2. Relevant equations
    Then I was being told if I want to calculate the total TIR then I have to use Pythagoras theorem.
    Why do I need to use that?
    What has Pythagoras theorem to do with this?
    Is it posible to draw it to get better understanding?

    3. The attempt at a solution
