Eccentricity of a compressed circular ring

  1. Dec 31, 2009 #1
    If an initially circular ring is made out of round by cutting out a section of the ring (delta g) and compressing the ring till the gap is approx zero is there an equation to describe the eccentricity of the circle?

    In a word, no. Eccentricity is defined for circles and ellipses. What you describe is probably neither.
