Torsional stiffness units

Therefore, torsional stiffness is called out in units of torque applied per angular unit of twist. North American manufacturers tend to use a variety of different units while Europeans typically use Newton meters per radian. Stiffness is the extent to which an object resists deformation in response to an applied force.

In the International System of Units , stiffness is typically measured in newtons per meter. Torsional Stiffness - S.

For one, in order calculate the natural frequencies of a part you need to . What is torsional rigidity ? T (θ) is called the torsional stiffness. From the above relation, image. The quantity is known as torsional rigidity and is.
