The torque necessary to generate a one-radian twist per unit length of the shaft is another definition for torsional stiffness.
GJ = T/ θ/L
Shear modulus (G) and polar moment of inertia are the components that make up torsional stiffness (J). The torsional rigidity of a material demonstrates its resistance to angular deformation. The following formula can be used to calculate a component's torsional rigidity::-
Torsional rigidity = G x J
The torsional stiffness for the component under the torque of T can be calculated using the:
GJ = TL/θ
What is Torsional Rigidity?
The torque necessary to create a one-radian twist per unit length of the shaft is called torsional stiffness.
