Who invented the spring?

The spring is an elastic element that uses the elasticity and structural characteristics of the material to maintain the specified relationship between deformation and load. Springs are also often used in life, such as our commonly used pens, slingshots, etc. Springs are mechanical parts that work with elasticity. Generally made of spring steel. It is widely used in machines and meters to control the motion of parts, ease impact or vibration, store energy, and measure the size of force. The types of springs are complex and varied. According to the shape, there are coil springs, scroll springs, plate springs, and stainless steel springs.
The spring is just an accumulator. It has the function of storing energy, but it can't release the energy slowly. To realize the slow release, the function should be realized by the “Spring + Larger Ratio Mechanism”, common in mechanical watches.
Springs have been used very early and long ago. Ancient bows and gongs are two springs in a broad sense. The strict inventor of the spring should be the British scientist Robert Hooke. Although spiral compression springs were already present and widely used, Hooke proposed "Hooke's Law" - the amount of spring elongation and acceptance. The force is proportional to the size of the force, it is in accordance with this principle, in 1776, the use of spiral compression spring spring scale came out. Soon, the springs used for watches built on this principle were also invented by Hooke himself. And the spring that meets "Hook's law" is the real spring.

ZhongDa  Enterprise is now a leading steel structure processing Company in North-East China with full annual production capacity of 40,000 tone.long span Steel Structure  factory warehouse, building ZhongDa Enterprise was founded in 2002.and with in 15 years of development, the company has grown to a multi-functional steel processing base, with total ground area of 100,000㎡ and factory size of 68,000㎡. From 2009, according to the market demand, Zhongda entered into a new field of long-span Steel Structure Bridge, and until 2016, Zhongda had manufactured over 60,000 tons of steel structured constructions for government projects, such as the Zone 2, Zone 3,Zone 4,overpass bridges, Benxi, Wuai river-crossing bridges etc. Zhongda  now has more than 400 employees and more than 50 highly qualified employees with relevant certificates, and was rewarded [Level One Nationalsteel ConstructionContracting Qualification " . In order to respond the national strategy of [the Belt and Road initiative",  Zhongda Enterprise established a Liaoning Zhongda Shenbang Industrial Co. LTD in China (Lioaning)free-trade district, with specific purpose of developing prefabricated building and modular buildings, with the initiation to maximize the advantage of Zhongda`s design and manufacture ability. Great feedback were received from customers around the world, including Europe, America, Australia, and Africa etc.   Zhongda Enterprise is now became a international steel structure construction company, with multi-functions of designing, manufacturing, marketing, and installation, with products including steel structured factories, shopping malls, bridges, residential buildings, modular and prefabricated  buildings. Zhongda Enterprise, as a member of the Modern Construction Industry, is willing to embrace the world and build a better home for everyone of us!
