Lesson: Chapter 11 — Turning Effect of a Force

11.2. Couple of forces 5 of 12

Question 5

What is the resultant force of a couple?

The right answer is the one marked above.

Zero. The two forces are equal in magnitude and opposite in direction, so F − F = 0.

One force multiplied by the distance is the moment of the couple, not its resultant force. They are two different quantities.
