Hi , i am using kangaroo2 to represent catenary curve.
I read the Kangaroo Manaul @DanielPiker wrote years ago , and i want to try if i can get the same curve under equal total loads with different numbers of segmentation.
To get similar behaviour for different discretizations of the same curve, you need to include a division by segment length in the ‘strength’ input.
This value is the k in Hooke’s law a.k.a. the spring constant, and can be found as EA/L, where E is the Young’s modulus, A is cross section area, and L is segment length.
In your test we can consider E and A to be the same for all cases, so just need to adjust by dividing by L.
Once we do this the different discretizations match up catenary (1).gh (28.8 KB)
