Moment of couple is defined as the product of perpendicular distance between the forces and magnitude of the force.
Mathematically,
Moment of couple = Force x Distance
Dimensional Formula of Force= M1L1T-2
Dimensional Formula of Distance = M0L1T0
Putting these values in the given equation we get,
Dimensional Formula of moment of couple = M1L2T-2
SI unit of moment of couple is Newton metre (N m)
