Torsion units
The calibrated torsion balance measured the force needed to twist the needle through a given angle. By bringing a similarly charged pith ball near the one on the needle, Coulomb determined the repulsive force between the charged balls as a function of their separation. ...

Torsion can be expressed in either pascals (Pa) or an S.I. unit Newtons per square meter, or in pounds per square inch (psi). In contrast, torque is expressed in Newton-meters (Nm) or foot pound-force (ft.lbf).
Torsional rigidity: Definition, Formula, Un It is a classical result of G. Higman [4] that every torsion unit of a commutative integral group ring is trivial. Hughes and Pearson [5] showed that there are two nonconjugate units of order 3 in U 1 ℤ S 3 , where S 3 is the symmetric group on three elements. These units cannot be conjugate to trivial units. Torsional rigidity is the product of shear modulus (G) and polar moment of inertia (J). It shows the resistance offered by a material to angular deformation. In the below figure, the opposite torques (T) applied to the shaft are trying to twist the shaft. and the torsional rigidity is working to oppose the twisting (angular deformation).
