Spring Constant vs. Stiffness Factor: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 2, 2024
Spring constant measures force per unit deformation in springs; stiffness factor indicates resistance to deformation in materials.

Key Differences

The spring constant quantifies the force needed to extend or compress a spring by a unit length. It is specific to springs or spring-like systems. In contrast, the stiffness factor refers to the general resistance of a material or structure to deformation under applied force.
