The resultant moment of a couple is called a torque. This is not to be confused with the term torque as it is used in physics, where it is merely a synonym of moment.

The student will readily conceive that the tendency of a couple which acts on a
free rigid body is to make the body turn round; and it is shewn in works on the
higher parts of mechanics that such is the case : the rotation takes place round a
straight line which always passes through a certain point in the body called its
centre of gravity, but is not necessarily perpendicular to the plane of the couple.

tend to turn ...

The present work aims at extending this technique in studying crack problems
within couple-stress elasticity, i.e. within a theory accounting for effects of
microstructure. As a first step, the technique is introduced to study finitelength
cracks under remotely applied shear loadings (mode II and mode III cases). The
mode II and mode III cracks are modeled by a continuous distribution of glide and
screw dislocations, respectively, that create both standard stresses and couple
stresses in the ...

We assume that the response of the material is governed by standard couple-
stress elasticity (Cosserat elasticity with constrained rotations). This theory falls
into the category of generalized continuum theories and is a particular case of the
general approach of Mindlin [13]. One of the earlier works that advanced ideas
underlying couple-stress elasticity was the treatise by the Cosserat H.G.

internal force system acting on the cross section labeled 1 (perpendicular to the
axis of the bar), we must first isolate the portions of the bar lying on either side of
section 1. The free-body diagram (FBD) of the portion to the left of section 1 is
shown in Fig. 6.1(b). In addition to the external forces F1, F2, and F3, this FBD
shows the resultant force-couple system of the internal forces that are distributed
over the cross ...

4–27 A couple is defined as two parallel forces that have the same magnitude,
but opposite directions, and are separated by a perpendicular distance d, Fig.4–
25.Since the resultant force is zero, the only effect of a couple is to produce a
rotation or tendency of rotation in a specified direction. For example,imagine that
you are driving a car with both hands on the steering wheel and you are making
a turn. One hand will push up on the wheel while the other hand pulls down,
which ...

An infinitesimal surface element transmits a force and a couple vector, which give
rise to nonsymmetric stress and couple-stress tensors. The former is related to a
nonsym- metric strain tensor and the latter to a nonsymmetric curvature tensor,
defined as the gradient of the rotation vector. This type of the continuum
mechanics was originally introduced by Voigt (1887) and the brothers Cosserat (
1909). In a simplified micropolar theory, the so-called couple-stress theory, the
rotation ...
