Question

If the moment of force is assigned a positive sign, then the turning effect of force will be in which direction?

Answer 1

1. Moment of force is defined as the product of force and the perpendicular distance between the line of action of force and the point about which the force is applied.
2. If the turning effect on the body is clockwise, the moment of force is the clockwise moment and as a sign convention, this is taken as negative.
3. Anticlockwise moment is taken as positive when the turning effect on the body is anticlockwise due to the force applied to be in the upward direction.

Thus, if the moment of force is assigned a positive sign, then the turning effect of force will be in an anticlockwise direction.
