PHY 101 Mechanical Equilibrium and Rotational Dynamics Objective Question
Take CBT

Question

Two equal and opposite forces whose lines of action do not coincide are said to form what?
Options
A An equilibrium system
B A balanced force system
C A couple
Correct Answer
D A resultant moment of zero
Correct Answer

Option C is the correct answer.

Detailed Explanation

A couple is specifically defined as a pair of two equal and opposite forces that are parallel but do not share the same line of action. This arrangement produces a pure turning effect (torque) with no net linear force.

Hint

Think about what kind of force system can cause rotation without translation.
