Stiffness Calculator

Calculate the stiffness, applied force, or extension of an elastic body using this online stiffness calculator.

Stiffness refers to the resistance of an elastic body to deformation when an external force is applied. It is a measure of how much the body displaces under the force along the same degree of freedom. In rotational systems, stiffness is the ratio of momentum to rotation. Flexibility or pliability is the inverse of stiffness. This online stiffness calculator can help you determine the stiffness, applied force, and extension by providing the other known values.

    • k = F / δ
    • F = k x δ
    • δ = F / k

    Where:

    • k = Stiffness
    • F = Applied Force
    • δ = Extension
