Question

Which of the following options is incorrect regarding moment of force?

• A. Conventionally, clockwise moments of force are taken as positive.
• B. Conventionally, clockwise moments of force are taken as negative.
• C. It is a vector quantity
• D. The S.I unit of moment of force is N m

Answer 1

The correct option is A Conventionally, clockwise moments of force are taken as positive.

Conventionally, clockwise moments are taken as negative moments and anticlockwise moments are taken as positive moments.

Moment of force is a vector quantity. It has both magnitude and direction.

Since moment of force = (Force perpendicular distance), S.I. unit of moment of force = N m.
