**Enriched Calculators**

Spring ForceIf you have a spring on hand and want to know its force for a given displacement, use this calculator. |
Spring DeflectionIf you have a spring and want to know the compressed length for a given applied force, use this calculator. |
Spring Rate kIf you need to know the needed spring constant that will give you a desired spring force for a given deformed length, use this calculator. |

Force and StressThis calculator in an extension of the basic Spring Force calculator above, providing the maximum shear stress in the spring along with the force. |
Range of Rate kIf you only have set of design specs, consisting of a range of compressed spring lengths and a range of desired spring forces, use this calculator. It will return a range of spring constants that will meet your design specs. |
Spring DesignerWith this calculator, you can start with an idea for a spring (geometry and material data) and calculate all resulting parameters (spring rate, max load, solid height, coil pitch, etc.). |

**Cyclic Load Calculators**

Spring ResonanceUse this calculator to find the first resonant frequency for a spring used in a dynamic loading environment. |
Spring FatigueUse this calculator to estimate if a spring used in a dynamic loading enviroment will fail from fatigue stresses. |
