Original Khojo Papers practice question — not from a past board paper.
Answer
When a body is in equilibrium under the action of coplanar forces, the sum of the clockwise moments about any point is equal to the sum of the anticlockwise moments about that same point.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
This is the condition for rotational equilibrium; translational equilibrium additionally requires the resultant force to be zero.
