प्रश्न
Define the moment of force.
उत्तर १
Moment of force — The turning effect of force acting on a body about an axis is called the moment of force.
उत्तर २
The turning effect produced by a force on a rigid body about a point, pivot or fulcrum is called the moment of force or torque. It is measured by the product of force and the perpendicular distance of the pivot from the line of action of force.
Moment of a force = Force × perpendicular distance of the pivot from the force.
