Spring is a kind of elastic element widely used in the mechanical and electronic industry, the spring can produce a large elastic deformation when loaded, and convert the mechanical work or kinetic energy into deformation energy, and after unloading, the deformation of the spring disappears and returns to the original state, and at the same time converts the deformation energy into mechanical work or kinetic energy. The ratio of the load to the deformation of the spring is called the spring rate, and the greater the stiffness, the stiffer the spring.
The role of springs
A spring is an elastic object that stores mechanical energy. Springs are usually made of spring steel. There are many spring designs. Its elasticity can be used to control the movement of parts, to soften shocks or vibrations, to store energy, to measure the magnitude of force, etc. It is widely used in life, such as automobile suspension springs, shock absorbing springs in the lower part of trains, spring scales in life, and springs in dynamometers.
Classification of springs
According to the nature of the force, springs are divided into: extension springs, compression springs, torsion springs and bending springs.
Extension springs are coil springs that are subjected to axial tension, and extension springs are generally made of round-section materials. When the load is not bearing, the rings of the extension spring are generally tight with no gap.

Features: Many different terminal devices or "hooks" are used to ensure the source of tension for the extension spring. Extension springs work in the opposite way of working with compression springs. Compression springs act in reverse when compressed, while extension springs act in reverse when extended or pulled. When the ends of the extension spring are pulled apart, the spring will try to pull them back together. Like compression springs, extension springs absorb and store energy. Unlike compression springs, most extension springs are usually under some level of tension, even without any load. This initial tension determines how tightly the extension spring coils without any load.
