applyForce on moving joint body?

I am having using applyForce when a body is moving ‘pivot joint’ body.

There is 3 parts to the joint and to move it as 1 I use this applyforce.
I have tried it on all 3 objects that are joint togther but I get a object moving up and toppling over to easy.

What is the rest of your physics body? The force will only be applied to the object you call it on. More sample code please! [import]uid: 8271 topic_id: 26479 reply_id: 107456[/import]
