Do you know what are the characteristics and functions of springs? Let’s introduce them for you,including these four functions:
1. Buffer function
A spring is installed between the frame and the wheel to make use of the elasticity of the springs to slow down the bumpiness of the vehicle. Therefore, every car above the spring also has a great use.
2. Vi-bro acoustic function
When the air is blown out from the harmonica, the accordion flows in the spring hole and strikes the reed, which vibrates and makes a beautiful sound.
3. Measurement function
How to make spring scale? It is within the elastic limit, the elongation (or contraction) of the spring is proportional to the external force. Use this property to make a spring scale.
4. Reset function
The springs deform under the action of external force. After removing the external force, the spring can return to normal state. Many devices and tools are reset using this property. Many buildings on the hinges, for example, are equipped with a return spring, which automatically appeases when people enter and exit. People also use this function to make automatic pencil, automatic umbrella and other items, very convenient.
