Question

Define moment of couple. Write its S.I unit.

Answer 1

Dear Student,

Moment of couple is the product of either of the forces of a couple by the perpendicular distance between them. The S.I. unit of Moment of Couple is Nm (Newton metre).

$M=F\times d$

​​​​​where, M = Moment of force
F = Force
d= perpendicular distance between the forces.
