Frame dragging is a theory which says that space is elastic, and particles in it will exchange energy with it. In the scientific world, elastic means that when you apply a certain amount of force to an object (which will cause it to bend) and then remove the force, the object will return to its original shape and energy state.
A Drag Link is a steering gear component that changes the rotary motion of the steering box to a link in a different plane or axis. It is used in a four-link steering mechanism. The drag link converts the steering box's sweeping motion to linear motion that pulls the tie rods, thereby turning the wheels of the vehicle. One end of the drag link is connected to the steering wheel via the Pitman arm and steering gearbox. The other end of the drag link is attached to the car frame by the idler arm. The length of a drag link influences the steering ratio. A damaged drag link affects the automobile's toe in and toe out settings.
