Question by photonoli · Apr 30, 2020 at 10:54 AM · rotation physics 3d

How to simulate 3d rotating gears with joint or constraints?

Basically, I have two gears in contact. One gear is twice bigger than the other. Both gears are 3d rigid bodies. I would like to force the second gear to have an angular velocity equal to minus two (-2) times the velocity of the first one.

So far, I have found a way to force the two gears to have the same angular velocity with a joint or a constraint. But, I did not find a way to apply a multiplicative factor (minus two in my situation).
