Which of the following is NOT a unit of moment of force?
APa
Bdyne cm
Ckgf m
DNm
Answer & Solution
Correct answer: A. Pa
1. Moment of force is force times perpendicular distance.
2. Nm, dyne cm and kgf m are all of the form force times length, so they are valid units.
3. Pa is Pascal, the unit of pressure (force per area), not moment.
4. Therefore Pa is not a unit of moment.
