Two equal and unlike parallel forces acting at two distinct points whose lines of action do not coincide constitute a
AResultant
BCouple
CEquilibrant
DImpulse
Answer & Solution
Correct answer: B. Couple
1. A couple is formed by two equal and opposite parallel forces at different points.
2. Their resultant is zero, so there is no straight-line motion.
3. However, they produce a rotation, and this configuration is called a couple.
