Nomenclature for Animations

FOR EXTENSION SPRINGS

Extension Spring Animation NomenclatureExtension Spring Animation Nomenclature

 

Our Online Spring Force Tester shows you visually how much force and deflection (travel) you can obtain from your spring safely. This is accomplished by running the spring design through our spring calculator to show true results. These numbers are true using our propietary software, Spring Creator which gives accurate results. Please DO NOT subject your spring to go past the maximum loads or maximum deflection or travel. Please see: Note of caution on max. Safe travel (Deflection).

 

Max. Load (ML)

Is the Maximum load or force you can place on the extension spring. If more load is placed on the spring, the spring will deform and not return back to its original length inside hook. Do NOT place more than the Maximum Load on the extension spring; For if you do add more than the Maximum Load, you will deform or possibly break the spring. Additionally the extension spring will not return back to its original length inside hook (overall length). You will also deform or possibly break the hooks on the ends of the extension spring.

Max Deflection or Max Safe Travel

Is the Maximum amount of deflection or safe travel distance you can extend or pull the extension spring. If more extension, pull or stretch is placed on the extension spring, the spring will deform and not return back to its original length inside hook (overall length). For if you do extend, pull or stretch the extension spring further, you will deform or possibly break the spring. The extension spring will lose load and force and fail to perform. Do NOT extend, pull or stretch the extension spring past the Maximum Deflection or Maximum Safe Travel Threshold.

If you do go past the maximum travel You will also deform or possibly break the hooks on the ends of the extension spring.

Note of Caution on Max. Safe Travel.

Just because there's room left to extend, pull or stretch the extension spring further doesn't mean you should. You should NOT and CANNOT go past the Max Safe Travel distance; For if you do extend, pull or stretch the extension spring further, you will deform or possibly break the spring. Additionally It will not return back to its original length. The spring will lose load and fail to perform. Do NOT extend, pull or stretch the extension spring past the Maximum Safe Travel Threshold.

Working Load Calculation

Enter a Load within the limits of the maximum load or Enter an Extended Length. The unknown value will be calculated for you when you click the Tab button.

Extension Spring Working Load CalculationExtension Spring Working Load Calculation

Load 1 (L1)

Is the 1st load point placed on the extension spring either in pounds of force (lbF) or Newtons (N). You can enter your load 1 in this feild that's within the maximum load (ML) allowed.

Extension Spring Load OneExtension Spring Load One

Load 2 (L2)

Is the 2nd load point placed on the extension spring either in pounds of force (lbF) or Newtons (N). You can enter your load 2 in this field that's within the maximum load (ML) allowed.

Extension Spring Load TwoExtension Spring Load Two

Load @ Extended Length

Is the Load or Force at a particular extended length of the extension spring

Compression Spring Loaded HeightCompression Spring Loaded Height

Distance Traveled / Deflection

Is a portion of your max. Safe travel / deflection in inches or mm.

Extension Spring Distance TraveledExtension Spring Distance Traveled

Length Inside Hooks

 It's the overall length from inside of one hook to the inside of the other hook

Extension Spring Length Inside HooksExtension Spring Length Inside Hooks

Extended Length

Is the extended length of your extension spring when a load or force is applied to it. 

Extension Spring Extended LenghtExtension Spring Extended Lenght

Rate (Lbs/In) (N-mm)

Spring rate, also known as spring constant, is the amount of force or energy it takes an extension spring to travel or extend an inch of distance or, in the metric system of measurement, a millimeter of distance. The units of measurement of rate in the English System are, lbf/in (pounds of force per inch) or N/mm (newtons per millimeter) in the Metric System.
