A, B and C are the three forces each of magnitude 4N acting in the plane of the paper as shown in Figure. The point O lies in the same plane. (i) Which force has the least moment about O? Give a reason. (ii) Which force has the greatest moment about O? Give a reason.
A, B and C are the three forces each of magnitude 4N acting in the plane of the paper as shown in Figure. The point O lies in the same plane. (i) Which force has the least moment about O? Give a reason. (ii) Which force has the greatest moment about O? Give a reason.

(i) Moment of force= Force x Perpendicular distance, as we all know.

Because the perpendicular distance between vector C and point O is the shortest,

As a result, vector C will have the smallest moment in relation to O.

(ii)Moment of force= Force x Perpendicular distance, as we all know.

Because the perpendicular distance between vector A and point O is greatest,

As a result, vector A will have the highest moment in relation to O.
