I am trying to use kangaroo 2 to simulate tension of a real fabric. In the 2.42 Release Notes, it says that on the **Length component**, the **strength parameter**…

…can be assigned real quantitative meaning, by setting the strength to the

spring constant in N/m, calculated as EA/L, where E is the Young’s modulus of the material in Pa,

A is the cross-sectional area in m 2 , and L is the rest length in m.

My question is on the **Length component**, there is a **strength parameter** and a **length parameter**. Am I correct in understanding that I am supplying the **strength parameter** with:

**(Young’s Modulus of the material)x(Cross-sectional area)**

and then using the **length parameter** with no input so that it takes every length of my mesh as my “rest length in m”, with Rhino units set to meters?

I guess I am wondering if the component itself does the division of EA/L to get the spring constant or if I am misreading something.

Thank you in advance for any help.
