|Turning Torso, Malmo, Sweden. This tower was designed to appear as if in a state of torsion. Actually it is not, but the appearance is a good example of what would happen theoretically if a turning force was applied to one end of the tower.|
Torsion can be seen in a circular-section rubber bar inscribed with rectangles and which is held at each end, with one hand twisting in relation to the other: the rectangles become skewed – or distorted. The state of strain that has distorted the rectangles is called torsion and consists of pure shear. The torsion that exists in the rubber bar will try to make it revert to its original shape.
 Torsion is expressed in:
- Pascal (Pa) – the SI Unit for newtons/m2, or
- Pounds per square inch (psi).
