Rotational Stiffness

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

rotational stiffnessRotational stiffness, abbtrviated as k, is the resist deformation of an object in response to an applied force.

 

Rotational Stiffness formula

\(\large{ k = \frac{M}{\theta}  }\) 
Symbol English Metric
\(\large{ k }\) = rotational stiffness  \(\large{\frac{lbm-ft}{deg}}\) \(\large{\frac{kg-m}{rad}}\) 
\(\large{ \theta }\)  (Greek symbol theta) = angle of the rotation \(\large{deg}\) \(\large{rad}\)
\(\large{ M }\) = applied moment \(\large{\frac{lbm-ft}{sec}}\) \(\large{\frac{kg-m}{s}}\)
