<u>Answer:</u>
The synergistic action of muscle groups to produce movement around a joint is known as a "force-couple".
<u>Explanation:</u>
"Force-Couple" is a bond between force and couple, it is the action of muscles or muscle groups moving jointly to generate movement around a joint in a synergistic manner. The movement is created by a single muscle pulling on a bone especially when people talk about movement and muscle.
For an instance in order to turn a steering wheel, the forces put in by two hands are considered as a couple. At points on opposite sides of the shaft, each hand holds the wheel. When applying a force equal in magnitude, the wheel rotates in the opposite direction.
Calculation of the moment/torque of a couple is done measuring the perpendicular distance between the two forces and multiplying the size of one of the forces.
