A couple consists of two equal and opposite forces acting along different lines of action. What is the net translational force due to a couple acting on a rigid body?

  1. A
    Equal to twice the magnitude of one force
  2. B
    Equal to the magnitude of one force
  3. C
    Zero
  4. D
    Infinite
View Answer & Solution

Correct answer · Option C

Zero

Explanation

Since a couple comprises two equal and opposite forces (\( \mathbf{F} \) and \( -\mathbf{F} \)), their vector sum is zero (\( \sum \mathbf{F} = 0 \)), producing pure rotation without translation.
