simple lever

I am trying to create a collapsable space frame. i am starting from creating a basic lever+fulcrum+load mechanism: can anyone help me locate if there is a pivot/fulcrum like component in kangaroo ?

or if there is another way to solve it?

This example is the closest to what I had been looking for. Even if I turn it into 3d, it does not provide enough the design freedom. This example is produced by geometrical intersection of circles, i was looking for something that has physics involved.

In the end I want to input varrying shaped polygon arches geometry and turn them into deploable space frames.
