(N/A) The moment of a couple is defined as the product of the magnitude of one of the forces and the perpendicular distance between the lines of action of the two forces.
Formula: $\tau = F \times d$
Where:
$\tau$ is the moment of the couple,
$F$ is the magnitude of one of the forces,
$d$ is the perpendicular distance between the two forces.
