(c) Figure 3 shows a force of 200N acting at the end of a plank of wood.
The force acts at right angles to the plank and at 3.0 m away from a pivot.

Calculate the moment of the 200N force about the pivot.
State the unit of the moment of the force.
Use the equation
moment of a force = force x distance at right angles to the direction of the force.

moment of the force about the pivot = _________________
unit = _________________
