Definition

1. Noun:
   • A type of mechanical spring: A "leaf spring" is a long, narrow, and curved spring. It is not a single piece but is made by stacking several long, thin strips (leaves) of spring steel on top of each other. These layers are held together at the center by a bolt or clamp. It is primarily used in the suspension systems of vehicles to absorb shock and support weight.
