Solution

Definition of Moment of a couple:
The tendency of a force is to rotate a body. It is measured by the moment of the force. The product of one of the two forces of a Couple and the perpendicular distance between their lines of action (called the arm of the Couple) is called the Moment of the Couple.
Moment of Couple ( τ ) = Force X arm of the couple
Solution:
Given,
Force=15N
Arm of couple =85 cm =0.85 m
Moment of couple = Force X arm of the couple
=15N X 0.85m
=12.75 N-m
conclusion:
Therefore the moment of a couple is equal to 12.75 N-m
