What are springs? 

Springs are common mechanical parts used in almost all engineering processes. Springs are usually created by heat treatment, cold working, forging, drawing, or stretch forming.

Spring is a coil of metal wire or other round-wire material that contracts or expands on the application of force. The contraction happens due to perpendicular forces acting on each end of the spring as they move towards each other. The tension causes the spring to store energy and makes elastic work easier and more efficient.

A spring mechanism can exert pressure, 'rotational' energy, or 'pulling' strength in various ways.

There are two types of springs: 

• Coil springs
• Leaf springs
