How Does the springiness of a telephone dial obeys hooke's law?

The springiness of a telephone dial obeys Hooke's Law, which states that the force exerted by a spring is proportional to its displacement from the equilibrium position, within the elastic limit. When the dial is rotated, the spring compresses or extends, creating a restoring force that attempts to return it to its original position. This behavior ensures that the dial can return to its resting state after being turned, demonstrating the linear relationship between force and displacement as described by Hooke's Law. Thus, the dial's mechanism efficiently converts rotational motion into an electrical signal through this elastic response.
