    Heights at various points along an arc | 
  2016-04-15 | 
   
    | 
  From Isiah: So I am working on a problem with a few friends; you have an arc with the center of its chord at 0,0. We also have a known sagitta and a known radius of curvature.
How do we calculate the height extending in both the positive and negative directions? 
Central sag: 2.48 
Chord length: 9.6 Answered by Penny Nom. |
