Springs: Structure, Material, and Function

The video tutorial explains what springs are, highlighting their elasticity and ability to stretch or compress. It discusses the materials used to make springs, emphasizing the need for metal in machine applications due to its durability and stiffness. The tutorial uses a paper clip to demonstrate how springs work, showing how coiling changes the metal's properties, making it easier to stretch or compress. The concept of pre-stressed springs and energy absorption is also covered.
