Question

Two equal and unlike parallel forces of magnitude 16 N act on a rigid body, such that moment of couple is 12 Nm. Calculate the arm of couple.

Answer 1

Moment of couple = 12 Nm

Force = 16 N

Moment of couple = Force × Arm of couple

∴ 12 Nm = 16 N × Arm of couple

∴ Arm of couple = `12/16` = 0.75 m
