The resultant force of a couple is zero.
A second answer (depending on the context of your question) is that a “Force couple” is a pair of equal and opposite forces that act on a rigid body.
In classical mechanics, coupling is a connection between two oscillating systems, such as pendulums connected by a spring.
A couple is defined as two forces (coplanar) having the same magnitude, parallel lines of action, but opposite sense. a steering wheel in a car; OR.
It appears naturally in the equations for many electromagnetic phenomena.If the force between an electron and a proton is used, the comparison between gravitational and electric force isA dimensionless constant which characterizes the electromagnetic force isSince the strong coupling constant has a value of about 1 in the energy range around 1 GeV, this suggests a value for the weak coupling constant in the rangeThe body of data describing the strong force between nucleons is consistent with a strong force coupling constant of about 1:Another quantity with those dimensions which occurs naturally in the interaction of radiation with matter is It is always equal to (F)(d)!For example, the forces that two hands apply to turn a steering wheelare often (or should be) a couple. The torque is stable, so the angular acceleration is constant. The International System of Measurement units used for torque is newton-meters or N*m.Even though newton-meters are equal to Joules, since torque isn't work or energy so all measurements should be expressed in newton-meters.Torque is represented by the Greek letter tau: τ in calculations.When it is called the moment of force, it is represented by M. (Because the sum of their horizontal and vertical components are zero) d, arm of the couple
Coupling Constants for the Fundamental Forces.
Work done by a torque can be intended by taking equivalence from work done by force.
In particle physics, two particles are coupled if they are connected by one of the four fundamental forces (In physics speak - no linear acceleration or translation.)

It does not produce any translation, only rotation. The moment (or torque) of a couple is calculated by multiplying the size of one of the force (F) by the perpendicular distance between the two forces (s). So you can attain it as a function of time.
Couples have pure rotational effectson the body with no capacity to translate the body in the vertical or horizontal direction.
A couple consists of two parallel forces that are equal in magnitude, opposite in sense and do not share a line of action. When they apply a force that is equal in magnitudeyet opposite in direction the wheel rotates. BUT, the resultant of a couple is not zero; it is a pure moment.
Instead of rotating around theshaft, the shaft would be loaded with a force tending to cause a translationwith a magnitude of twice F. If the forces applied by the two hands wereunequal, there would again be an unbalanced force creating a translationof the "system." A pure couple always consists of two forces equalin magnitude.
This coupling constant is also called the "fine structure constant" since it shows up in the description of the fine structure of atomic spectra. A couple is two equal forces which act in opposite directs on an object but not through the same point so they produce a turning effect. In physics, two objects are said to be coupled when they are interacting with each other.
A couple is a pair of forces, equal in magnitude, oppositely directed, and displaced by perpendicular distance or moment. If both hands applied a forcein the same direction, the sum of the moments created by each force wouldequal zero and the wheel would not rotate.
