    Couple or turning moment are nothing but torque.

    it is also called a rotating force.


    it is the amount of leverage that has to be applied to a certain heavy object in order to turn it about its axis of rotation.

    direction however means the direction of rotation (clockwise or anticlockwise).

    i think in couple there are two forces(equal in magni but oppst in dircn) and in turning moment only one force(acting about a axis).
    then how they can be equal.

    So u must be thinking that those 2 must cancel... but my friend, these two are not acting at a single point(if they would be acting at a point then being in opposite direction they should cancel out) but they act on different points of same body, and hence torque is generated,and the object rotates😀.

    but rahul they are acting in the same plane i think. so the net affect of force must have to be cancel out isn't it? otherwise couple will not be formed if they are not in same plane.
    forces should/must be in same plane if they are forming a couple

    Yes the net force is zero!! but the "moment of force" is not zero, and hence the body experiences torque, I was talking about Moment of force and both have same direction and hence not equal to zero.
