Calculation Formula

k = k_spring / (1 + (m_eff / k_spring))

Where:
k = Stiffness Coefficient (N·m⁻¹)
k_spring = Spring Constant (N/m)
m_eff = Effective Mass (kg)

How to Use This Calculator

  1. Enter the Spring Constant (k_spring) in N/m. This is the stiffness of the spring.
  2. Enter the Effective Mass (m_eff) in kg. This is the mass that the spring is effectively supporting.
  3. Click the Calculate button to compute the stiffness coefficient.
  4. The result will be displayed in N·m⁻¹.
  5. Use the Reset button to clear all inputs and start over.

Working Principle

The stiffness coefficient (k) represents how stiff a spring system is. It accounts for both the spring's stiffness and the effective mass it's supporting. The formula used is:

k = k_spring / (1 + (m_eff / k_spring))

This formula adjusts the spring constant based on the effective mass, providing a more accurate measure of stiffness in dynamic systems.
