[ODE] Gears...

[Thomas Paviot]

Hello,

Did everyone ever try to simulate gears with ODE?

If i have two parallel axis, i.e. axis 1 and axis 2, and two gears of 
radius r1 and r2, it's equivalent to set a kinematic relation for the 
angular velocities of the  two axis : w1/w2=-r2/r1,
or a momentum equality:
M1/M2=-r1/r2 if we consider there is no power loss and M1w1=M2w2 (abs 
values)

I don't see how to do. Any idea?

Thomas
