Mechanical simulation, contact between moving bodies

Grasshopper Kangaroo

HI

as usual i am struggling in order to arrange this simple simulation , i want to simulate traslation of body1 and simulate rotation of bodies 2 accordingly

i think that K2 curvecollide could be the tool to use to estimate the tranformation to be applied to the bodies but the definition i made does not work

any suggestion on the most convenient way to approach the problem as lomg as on how to get the below definition to work ?

Is this the behaviour you are after?:

many thanks @DanielPiker

Yes thats in part what i want , beside this the lever 2 ( slave ) is pushed against 1 by a spring in a manner that contact is always guarantee , 1 is the master must touch a basement to avoid it to move along -Y until 1 and 2 loose contact.

i tried to introduce force wo basement and of course 1 and 2 looses contact immediately..

i then tried to add a basement but im not able to constrain it…it moves

To add a curve to the collisions where the interaction is only one-way (it affects the other curves, but is not affected itself), connect it to the P (PassiveCurves) input

Daniel ,

thanks again for your prompt support

Question : would you suggest using a classic ( geometrical) approach or is it K2 the right choice ?

thanks , regards
