Q:How about the size of the elasticity?

Also called elastic force". The object by the force deformation, if the external force is removed, the object can return to its original shape of the elastic force, called "". Its direction is opposite to the external force that causes the object to deform. There are many different kinds of deformation, so there are different forms of elasticity. For example, when a heavy object is placed on a plastic sheet, the bent plastic should be restored to its original state and produce upward elasticity, which is its support for the heavy object. Hanging an object on a spring, the object stretched the spring, the elongated spring to restore the original state, resulting in upward elasticity, which is its pulling force on the object. Not only plastic, spring and so on can occur deformation, any object can deformation, no deformation of the object does not exist. However, some of the deformation is obvious, can be seen directly; some deformation is very small, must be aware of the instrument.

Q:Want to practice how to use pectoral muscle spring expander

Spring cable name chest expander, mainly in order to exercise chest muscle and design. Of course, spring also can assist in other parts of the exercise chest muscle.General situation, you can consider four groups per day, each group of fifteen can, this can be based on their own ability to carry out, proper exercise can be, it is necessary to adhere to exercise will be effective.

Q:What is spring pressure and height?

Press the compression spring to the point where each circle is tightPress height = = (total coil number -0.5) * steel wire diameter

Q:How should we choose the spring material?

The selection of spring materials shall be determined according to the nature of the load, stress state, stress magnitude, working temperature, working environment and service period of the spring.

Q:What are the categories of springs?

Linear springs, linear springs from top to bottom of the thickness and density unchanged, the elasticity coefficient for fixed values. The dynamic response of spring of this design can make the vehicle obtain more stable and linear, is conducive to better control the vehicle driver, for vehicle performance orientation and competitive disadvantages of vehicles is of course affect comfort.

Q:What kind of spring has the best performance?

The length of the spring, with a number of differences between the spring, will affect the product intensity consistency.

Q:In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position"

In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position"

Q:Spring dynamometer and spring balance what is the difference

The principle is similar, but the uses are somewhat different

Q:How to choose spring steel material?

Spring steel is selected on the basis of the section size of the spring, such as high carbon steel 65, suitable for production in the spring of 12 ~ 15mm under section 60CrMnA, suitable for the production of spring and the car less than 50mm in diameter with heavy-duty spring. The 30W4Cr2VA is used to make heat-resistant spring for work below 500 degrees centigrade. Generally, hot forming springs are generally quenched and tempered at moderate temperature to obtain a structure with a maximum elastic limit and fatigue properties

Q:The glass door spring is generally guaranteed for several years

Quality and price are pretty much the same. Many other miscellaneous brands of spring can be guaranteed for five years, three years it is best to begin with a reliable brand
