Explanation:

  • A leaf spring is a simple form of spring, commonly used for the suspension in wheeled vehicles.
  • It is also called laminated or carriage spring.
  • Leaf springs are formed by bending.
  • They are made of long strips of steel.
  • Each strip is named as Leaf.
  • The longleaf is called Master Leaf, and it consists of eyes at its both ends.
  • Laminated springs are generally loaded at the centre and supported at ends
