Moment of Couple – this term in physics is based on an understanding of 2 concepts, the first one is ‘moment’ and the second one is ‘couple’. The moment in physics denotes the turning effect and Couple in physics is discussed in our post on Couple – you can read it here.
Moment of Couple is the cumulative turning effect produced by a ‘couple’ of forces and its magnitude is the product of either force of the couple and the perpendicular distance between the two forces of the couple (or couple arm length).
Moment of couple Formula
The magnitude of Moment of Couple = Magnitude of either force of the couple x couple arm length
