Q: Is spring steel manganese steel?: Manganese steel and spring steel are the names produced under different classifications. The spring steel is classified from its use, and manganese steel is classified from its constituents. Spring steel also contains manganese, which is a kind of manganese steel.

Q: Want to practice how to use pectoral muscle spring expander: Every day until the last time I can not pull itFull pullExercise is a long process

Q: Hydraulic diagram of the one-way valve has two kinds of drawing, with a spring, without a spring, what is the difference between automatic reset function is not? Without a spring, it will not be repeated: General one-way valve is spring to reset, as for drawing may be the standard of drawing is not the same. As long as no oil passes, it closes.

Q: What kind of production equipment does spring factory usually have?: Spring testing machines; fatigue testing machines; torsion testing machines; spring tension and compression testing machines

Q: What is flat steel? Plain carbon flat steel? Spring flat steel: Flat steel, also called flat steel strip, is a long thin steel with a rectangular cross-section. According to the production process, it can be divided into hot rolled flat steel strip, fine shearing flat steel belt and cold drawn flat steel belt.Ordinary carbon flat steel - the component is ordinary carbon structural steel, suitable for wide range.Flat spring - flat steel used for making spring plates of automobiles, containing manganese.

Q: What is an independent bagged spring?: Independent spring: there are different springs, respectively, according to different weight, set up independent spring in different locations. Of the two men lying on it, one rolled over or left, and the other was not affected at all. Two mattresses in the middle area, the spring has different support strength, so won't feel sleep in the two bed crevice.

Q: What kind of spring has the best performance?: Spring outside diameter, the same spring at both ends of the outer diameter and the middle of the outer diameter is not the same, unlike the spring, the force has a slight impact. The same batch is very different from each other, indicating that the machining accuracy is very poor.

Q: The shop glass spring door is too tight, how to adjust?: It is better to ask professionals to deal with the danger!

Q: How to process Spring Steel: Spring steel has excellent comprehensive performance, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization, precise shape and size).

Q: Physics high school. Why does a spring fall to the lowest point and the acceleration a must be greater than the acceleration of gravity g ah. Seek expert: Is the map tilted?.Look at the picture. It means that a naturally stretched spring is placed vertically and then put a mass of m at zero initial speed.If dropped to the lowest point, the speed of the object v=0, object by the acceleration of gravity g down, if not spring to give it an g greater than or equal to the acceleration, the object will continue to fall, do not conform to the original intention of "low".So the acceleration inside the spring must be greater than or equal to g.
