Algodoo

It's NOT symmetrical. Take a look at the center line. The whole structure is shifted to the right by 0.5 meters, which is stretching the springs on the right side of center, and compressing the springs on the left side of center. So, when the circles on top fall down, they tend to roll to the left because of the offset spring tension. Does that make sense?

Hello? Are you there?.... I was wondering if you agree with my findings? Please reply.

Thanks

Sorry, i was sleeping, and didnt get on algodoo for a while, but is there a way to make it symetric without messing up the current structure (have the same structure as to the right)?

I use the grid, and make everything snap to grid points. That is how I make things balance and symmetric.

I did use the grid! i use the grid for prety much all o fmy creations! when you go into one of my creations, and then turn on grid befor unpausing, you will notice its prety much aligned!

Well, then I cannot explain what happened. Maybe someone else has some ideas?

ok...

It falls because the top left circle falls down first, the circle has a spring constant
different form the other springs. Mabye the center of gravity is imblanced so the structure fall down.

That's my guess but I think maybe somenoe has a different awnser.

It's because the forces of algodoo make it do dat but gravity disabled will help.

I played around with this scene again, and after readjusting everything so that the entire structure is balanced, and all springs are balanced, then it doesn't fall. So, the reason why it was falling is because of my first comment above when I said that the structure was not balanced. That's it! Just a basic issue of not being careful enough when constructing it to be sure that everything is balanced. Oh, and one more important thing..... You have to make it so that everything is stable when the scene is started. The way you designed it is NOT stable, and so the top structure falls onto the rest of the structure knocking the entire thing to one side. So, after making sure that everything is balanced, you also need to stabilize that top structure so that it doesn't fall when the scene starts.

Also the springs are off so it tlits.
