1. What is extension spring used for?
Applications for extension springs include automotive interiors and exteriors, garage door assemblies, vise-grip pliers, carburetors, trampolines, washing devices, farm machinery, toys as well as thousands of other uses.
2. How are extension springs rated?
All extension springs have a rate of pounds per inch of extension. Example: Lets say your spring is 10 inches long and has a rate of 10 lbs per inch / of extension . This means if you pull the spring 1 inch in distance it will take you 10 lbs of force to do so.
3. What is the difference between compression and extension springs?
One way to describe the primary difference between compression and extension springs is their load at zero deflection. Compression springs have zero load at zero deflection. Extension springs, on the other hand, experience a load at zero deflection due to their initial tension.
4. Can compression springs extend?
Compression springs differ from extension springs in regards to how they work. While extension springs become longer under a load, compression springs become shorter. Compression springs are designed for use in applications where two components try to push towards each other.
5. How are springs used in everyday life?
They're often used in everyday electronic toys, and in the batteries we use to make them come to life. Springs have been important to the toy making industry long before electronic toys. From the Jack-in-the-box to wind-up toys, many toys using springs have become iconic classics and are still popular today.
