Can pistons be prevented from stretching?
-
I'm trying to simulate hydraulic pistons; I'm using them to pivot a very heavy pivoted platform which is not counterbalanced and hence is incredibly top heavy.
In the real world some hefty hydraulics would be able to maintain the load and allow the platform to be controlled but whatever I try in sketchyphysics (2) results in the joints stretching apart (be they sliders or pistons). Basically what I need is an absolutely all-powerful piston/controlled slider which has an absolute maximum and minimum and is not subject to stretching past the specified limits.
Is there anything that can be done to achieve this? I have attached an image of the funfair ride model I'm making to illustrate what I'm trying to do here.
Cheers

The strength of a joint is directly related to how big (massive) the objects connected to it are. If you can post the model I can make some specific recommendations.

I had to PM the file to you as Firefox kept crashing when I tried on this thread!?

My browser kept crashing when I tried to attach this to the forum post so I tried here, assuming this posts it works! Odd...
My model basically needs to defy the standard physics of this I think. I can think of a few redesigns to change how the tilting mechanism works on this one although that tends to destabilise the central pillar. I know these things are possible in real life, I've seen engineering and funfair rides which do what I'm trying to do (in part at least) - I just don't know how to go about them in this. I guess in this scenario the tilter needs counterbalance, but as there is no weight control I don't see how to do this too easily.
Thanks in advance for any help, it is much appreciated!
