Greetings all:

I am interested in this thread regarding calculating the profile of prestressing cables. What I have is slightly different in condition. I am no math wizard, unfortunately.

I have a beam of length L and cable profile (reverse parabola).

What I know are the following:
1. Coordinate (x1,y1) --> Profile of tendon at high point @ x = 0
2. Coordinate (x2,y2) --> Profile of tendon at low point @ x = L/2
3. Coordinate (x3,y3) --> Profile of tendon at high point @ x = L

Is there an easy way to generate the profile of the cables such as shown in this link (figures 4,5 and 9a)
