I am working on a Motion Analysis model for rotating a tube.
So it is a tube, supported by 4 wheels. One wheel is driven.
I have added gravity, and solid body contact between the tube and the wheels.
When I run the study, the driven wheel turns, and the tube turns also. The other 3 wheels ( which also have a solid body contact ) don't turn, which apparantly should, by friction and weight.
Can anyone tell me what I am doing wrong?
