Define the moment of a force about a point and state its SI unit.
Original Khojo Papers practice question — not from a past board paper.
Answer
The moment of a force about a point is the product of the magnitude of the force and the perpendicular distance of its line of action from that point. Its SI unit is the newton metre (N m).
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The moment measures the turning effect of the force, and it is a vector quantity whose sense is either clockwise or anticlockwise.
