Strength of Materials: Torsional Striffness



Torsional Striffness

Sometimes it might be necessary to calculate the torsional stiffness of a part. The reason for this could be to conduct a vibrational analysis, or to get a general idea of how strong that part is when the loading is not known. To calculate torsional stiffness equation 1 would be used.

How to calculate torsional stiffness (1)

k = Stiffness

T = Torque

Φ = Angle of Twist

J = Polar Moment of Inertia

G = Shear Modulus

L = Rod Length
