Answer:
To answer the first question, the moment is equal to the force multiplied by the perpendicular distance from the pivot. So the moment in this case is 12 x 0.2 = 24 Nm. For the second question, the total clockwise and anticlockwise moments must be equal for an object to not turn. If the clockwise moment is greater than the anticlockwise moment, the object will turn clockwise, and if the anticlockwise moment is greater than the clockwise moment, the object will turn anticlockwise.
