Question

The moment of a force about a given fixed point depends:

• A. Only on the magnitude of force.
• B. Only on the perpendicular distance of force from the axis.
• C. Neither on the force nor on the perpendicular distance of force from the axis.
• D. Both on the force and its perpendicular distance from the axis of rotation.

Answer 1

The correct option is D Both on the force and its perpendicular distance from the axis of rotation.

Let an object be pivoted at O.
Moment of force about the point O is the product of force and the perpendicular distance between the axis of rotation and line of action of force.
Hence, it depends on both of them.
