This section is very complex. Is there an object or picture you have sampled for drawing this section?
Rather than correcting this model, it will be easier to redraw. However, it must be ensured that each piece is solid when redrawn.

This is a message sent by mistake. It needs to be deleted. I did not delete it. Sorry.

If you can not find a solution, do you share the skp file?

In my opinion, it is from the centrifugal force.
I can not help you with this because I do not have top level knowledge. If you ask this question "http://sketchucation.com/forums/viewtopic.php?f=323&t=64521&start=60" you can get better information.

1. The engine connection must be at the center of the wheel, not away.
2. Some settings should be as I do.

Follow these steps.

Would you share the skp file, please.

For Msphysics, I used "Convexify" to divide the object shown in the figure into convex pieces, but I did not create the division process. What would be the reason?

Do you upload the skp file.

You want it to look like in the pictures. You can use Round Corner plugin.

Is it possible to move or rotate a model with a joint connected to it?
Please click on the picture.

To ensure smooth movement, how should the green piece connect to the blue piece?

How to convert a model created with MSPhysics 0.9.9 to 1.0.0.

Thank you very much for your time and information.

The model in the attached file hangs and disintegrates after a period of working properly. What would be the reason?

Hi, Anton,
My purpose is to move the bike by chain, just like it is in a real bicycle. If I understand correctly, it is not possible to do this with MSPhysics. Is it true?

I'm trying to move this bike. But I have not been fully successful. What I do not know, what I know wrong and what my mistakes are? Thank you.
