The moment of a force about a pivot is equal to what ?
Answers
Answer:
Moment. The turning effect of a force is known as the moment. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn.
Answer:
The product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn.

- The principle of moments states that when in equilibrium the total sum of the anti-clockwise moment is equal to the total sum of the clockwise moment.
When undoing a nut fastened to a screw by hand one realizes that the amount of force required is a lot greater than when undoing the same nut using a spanner. The spanner increases the distance between the fulcrum and the line of action of the force, thus for the same force, a greater moment is obtained.
