# Rotational Stiffness

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

## Rotational Stiffness formula

\(\large{ k = \frac{M}{\theta} }\) |

### Where:

\(\large{ k }\) = rotational stiffness

\(\large{ \theta }\) (Greek symbol theta) = angle of the rotation

\(\large{ M }\) = applied moment
