Twisting, also known as torsion in technical terms, refers to the deformation of a body due to a moment acting around its longitudinal axis.
In addition to twisting, the resulting shape is also referred to as twisting or torsion. Together with tension (elongation), compression (compression), shear and bending, torsion forms the mechanical load types.
The distinction is made depending on the point of application and the direction of action of the force caused. In practice, shafts are the component most affected by torsional stress. They transmit rotational movements and are therefore subject to torsional forces.
