+This example shows a simple setup with a dynamic car body physics object and two dynamic wheels physics object joined together with a joint of type "hinge". The hinge joint can simulate an axle or a pin on which other object is rotating in respect to the base. The example shows how to create, destroy and change properties of the joints.
 
 The setup consists of four game objects. The *game.project* physics *GravityY* property is set to -500 to match the scale of the setup.
