In the program I try to simulate the rise of the attic stairs. When lifting them, i would like to move the feet of these stairs automatically through the wheels and the fixed wire.
In SW, I can simulate gears and pulleys, but for my case, I have no idea how to simulate a wire that is fixed at both ends.
The accompanying drawings show that the wire is fixed on the AB plate of the house and at the end of the periphery of the legs (red).
It is routed through a blue roller.
When the steps rise, this wire automatically closes the feet.
How do I define this wire when I move the stairs up or down so that the legs move in accordance to a wire assembly?
