The distance between the forces acting in the couple is

Explanation

Explanation : Couple When you use two hands to turn the handlebars of your bicycle or the steering wheel of your car you are applying two parallel forces to the same object. These two forces are not in equilibrium because they do not act in the same straight line . They are called a couple and have a turning effect or moment . Important Points Moment – The moment of a couple is the product of the magnitude of one of the forces F and the perpendicular distance d between the two forces. M = Force × perpendicular distance A couple is a pair of force acting on an object on an object which Are equal in magnitude and opposite direction Do not act along the same straight line Apply a moment to the object and so tend to turn it Do not produce a single resultant force and so do not tend to move it from one position to another
