# Spring Stiffness Calculator

The term stiffness refers to the rigidity of an object. It is a measure of the extent to which the string withhold to resists deformation in response to the applied force. Spring stiffness refers to the force that is required to cause the unit deflection. A more flexible object would have less stiffness and vice versa. Use our spring stiffness calculator to calculate the rigidity of a spring based on the number of coils, shear modulus, the diameter of spring, mean coil diameter and shear stress.

Code to add this calci to your website  #### Formula:

s=(64 × n × (m/2)3 × f)/(d4 × g × 103) Where, s = Spring Stiffness n = Number of Coils g = Shear modulus d = Diameter of spring (metre) m = Mean coil diameter (metre) f = Spring Force
