...distance. Such a pair of forces may cause a body to revolve around an axis. The moment of a couple is the product of one of the forces and the perpendicular distance between their lines of action. One couple is in' equilibrium with another when the moment of the one equals the moment of the other,...

...the tendency which a couple has to turn a body round an axis, ie its torsional raliie, is measured by the product of one of the forces and the perpendicular distance between them ; eg PX BC (Fig. 353). Considering P alone, as to its torsional value (or tendency to turn a body...

...Since these two forces, T and C, are equal, their moment, which is the resisting moment of the beam, is equal to the product of one of the forces and the distance between them. Hence we may write for the resisting moment of the beam M = Td' = Afd' = pbdfd'...
