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: For small spheres, the energy is conserved from the free fall to the ultimate spring compression equal to the maximum value of XMgX=0.5kX^2 (this formula is obtained by integration, do not know if you have no calculus)Calculate X=2mg/k, then the lowest point is the resultant force of the ball is kX-mg=2mg-mg=mg, in the direction of acceleration, the size is exactly equal to GIf the ball is considered to fall from high, then the energy conservation before it converts the energy of the potential energy into springs is naturally more, and the acceleration of the lowest point ball is greater than g

Q:How about the size of the elasticity?: Spring elastic deformation, the elastic limit, the elastic force with the elongation of the spring (or shorten) is proportional to the length (or the length of the spring and the pulling force is proportional to F=-kx (), or delta F=-k delta x). Where k is called the coefficient of stiffness (as a coefficient of rigidity or elasticity) of a spring, in numerical terms equal to the elasticity of a spring when it is stretched (or shortened) in unit length. The unit is Newton per meter, and the symbol is N/m. The K value is related to the nature of the material. The difference between the stiffness and stiffness of springs is that they have different stiffness coefficients. Moreover, the stiffness coefficients of different springs are generally different. The expression in the sign spring caused by its elongation (or compression) in the opposite direction. The law was discovered by British scientist Hooke, known as Hooke's law.

Q:What kind of material does spring have?: In some specific occasions, such as pH and humidity, we often use stainless steel to make springs.The material of the die spring is usually made of chrome alloy steel. Chromium alloy spring steel has the characteristics of high temperature resistance, great rigidity and long service life.

Q:How should we choose the spring material?: In determining the material section, shape and size, should be preferred in the national standard and standard series size, try to avoid using non standard materials.

Q:What are the categories of springs?: The tension spring is a coil spring that bears axial tension. In the case of no load, the coil between the coil and the coil is generally tight and without gaps.

Q:Spring dynamometer and spring balance what is the difference: The principle is similar, but the uses are somewhat different

Q:The glass door spring is generally guaranteed for several years: ,expect a warranty to ensure the quality is not very reliable.

Q:The glass door spring is broken. How much would it cost to change it?: The price of the spring itself is about 200-800, plus part of the labor cost. After all, it's very expensive. There are about 150 of the spring, but the quality is not good, or safety first. Labor costs are probably about 120. Specific prices should be based on your actual situation, you and the master speak.

Q:Buffer spring buffer for automobile: Next, put a soapy water or lubricant on the loose coil spring. Then, insert a strong buffer of soap, water or lubricant into the loose spiral spring gap, and then release the car body after confirming it.Finally, the distance between the damping springs is a matter of concern for mounting the shock absorber. The distance between the springs is equal to the length of the shock absorber. If it is more difficult to squeeze by hand, loosen the screw of the shock absorber, and let the damping spring relax 2 - 3 centimeters.

Q:What's the spring material to?: 1, with alloy spring steel, respectively, there are several kinds of steel: 55Si2Mn or 50CrVA and 30W4Cr2VA, these alloy spring steel;2, manufacturing process:Coil the machine first into the spring and then proceed with the proper heat treatment process to get the spring you need.
