Torque vs. Torsion: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 8, 2024
Torque is a measure of the force causing an object to rotate, whereas torsion refers to the action of twisting or the state of being twisted, especially of one end of an object relative to the other.

Key Differences

Torque is a concept in physics that describes the rotational equivalent of linear force, specifically the force that causes an object to rotate about an axis. On the other hand, torsion is the stress or strain produced in a body when it is twisted around its axis.

The magnitude of torque is calculated as the product of force and the distance from the rotation axis (lever arm), and it's a vector quantity. In contrast, torsion refers to the action or the result of twisting, often involving the application of torque, but it focuses on the effect of the twisting on the material or object.

In engineering, torque is crucial in designing machinery and vehicles, as it determines how effectively a force causes rotational motion. Torsion, however, is a factor in material science and structural engineering, as it deals with the deformation and stress on materials due to twisting forces.

Torque is a fundamental aspect in dynamics, determining how fast an object will spin or stop spinning under a given force. Torsion is more about the internal reaction of materials when subjected to torque, affecting their mechanical properties.

Torque and torsion are related, as torque can cause torsion, they address different aspects: torque is about the cause of rotation, and torsion is about the effect of twisting forces on objects or materials.
