Stiffness

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

stiffnessStiffness, abbreviated as k, is the resistance of the elastic deformation of an object that applies to both compression and tension.

 

Stiffness Formula

\(\large{ k = \frac{F}{\delta} }\)   

Where:

 Units English Metric
\(\large{ k }\) = stiffness \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ F }\) = applied force \(\large{ lbf}\) \(\large{ N}\)
\(\large{ \delta }\)  (Greek symbol delta) = displacement \(\large{ lbf }\) \(\large{N}\)
