Calculate spring constant (k), force, displacement, potential energy, and natural frequency using Hooke's Law. Supports series and parallel spring combinations and simple harmonic motion analysis.
Enter force and displacement to calculate spring constant (stiffness)
The force exerted by a spring is proportional to its displacement: F = kx, where k is the spring constant.
| Spring Type | Typical Range (N/m) | Applications |
|---|---|---|
| Soft Spring | 1-100 N/m | Pens, toys, light mechanisms |
| Medium Spring | 100-10,000 N/m | Suspension, door hinges, valves |
| Stiff Spring | 10,000-100,000 N/m | Heavy machinery, industrial valves |
| Very Stiff Spring | >100,000 N/m | Vehicle suspension, presses |

Calculate spring properties using Hooke's Law, the fundamental principle describing spring behavior. Our calculator determines spring constant, force, displacement, potential energy, and natural frequency for mechanical systems, helping engineers and students analyze spring-based mechanisms.
The spring constant (k), also called stiffness, measures how much force is needed to stretch or compress a spring by a unit distance. A higher spring constant means a stiffer spring that requires more force to deform. Hooke's Law states that the force F exerted by a spring equals the spring constant k times the displacement x from equilibrium.

In series, springs are connected end-to-end and share the same force but have different displacements. The equivalent constant is less than any individual spring. In parallel, springs share displacement but forces add up. The equivalent constant is the sum of individual constants.
