Answer:
(a) An introduction to moments and mechanical forces of rotation
Forces can cause an object to rotate and the turning effect of the force is called a moment.
If a resultant force acts on an object about a fixed turning point (the pivot) it will cause the object to rotate e.g. turning a nut with a spanner, applying a screwdriver, opening a door fixed on hinges. The pivot might also be called the fulcrum.
The rotational or turning effect, the moment, has a magnitude easily calculated from the formula:
