Two forces forming a couple are separated by a distance of 25cm. If one of the forces equals 40N, what is the moment of the couple?
1000 Nm
500 Nm
10 Nm
5 Nm
1.6 Nm
Correct answer is C
The moment (or torque) of a couple is calculated by multiplying the size of one of the force by the perpendicular distance between the two forces.
Given: F = 40N; d = 25cm = 0.25m
Moment = 40 x 0.25 = 10Nm.
