The twist or deformation of a body set up by a torque.
Torsion Theories
Torsion of Solid Sections
Torsion of Closed Thin-Walled Sections
Shear stress due to torsion in a thin-walled noncircular shell can be calculated as follows (Lindeburg 2003):
<tex>\tau = \frac{T}{2At}</tex>
where
- <tex>\tau</tex> ... shear stress
- <tex>T</tex> ... applied torsion
- <tex>A</tex> ... area enclosed by the centerline of the shell
- <tex>t</tex> ... sheel thickness
