See it on the paper →The pylons are spaced equally so that the weight of the cables on each side of the pylon balance. This means the pylons are in equilibrium. State the resultant turning effect on the pylons.
See it on the paper →Comprehensive responses • Some candidates correctly determined the force by dividing the moment by the distance. • Some candidates gave the correct unit for a force. Limited responses • Some candidates multiplied the moment by the distance. • Some candidates stated that the unit for force is the newton-metre (N m).
