Springs have been widely used for a long time. It is an accumulator that has the function of storing energy. The ancient bow and crossbow were two types of springs in a broad sense.
Now let's talk about the functions of springs:

There are springs installed between the frame and wheels, which use the elasticity of the springs to slow down the bumps of the vehicle. So the springs on each motor vehicle are also quite useful.
2. Vibration sound generation function
When air flows from the spring hole in harmonica and Accordion, it impacts the reed, and the reed vibrates to make a beautiful sound.
3. Measurement function
How is the Spring scale made? It means that within the elastic limit, the elongation (or contraction) of the spring is proportional to the external force. The Spring scale is made of this property.
4. Reset function
The spring undergoes deformation under the action of external force, and after removing the external force, the spring can return to its normal state. Many devices and tools utilize this property to reset. For example, many building doors have reset springs installed on their hinges, and when people enter and exit, the doors will automatically comfort them.
