Rotational stiffness is torque applied over angle¶

Rotational stiffness is the extent to which an object resists rotational deformation.

rotational_stiffness¶: Rotational stiffness of the body. See torsion_stiffness.

Symbol:: kappa
Latex:: \(\kappa\)
Dimension:: force*length/angle

torque¶: torque applied to the body.

Symbol:: tau
Latex:: \(\tau\)
Dimension:: force*length

angular_distance¶: Angle of deformation. See angular_distance

Symbol:: theta
Latex:: \(\theta\)
Dimension:: angle

law¶

kappa = tau / theta

Latex:: \[\kappa = \frac{\tau}{\theta}\]
