Learning objectives
What the syllabus expects you to be able to do.
- 1.5.2.1Describe the moment of a force as its turning effect, with everyday examples.
- 1.5.2.2Define and use moment = force × perpendicular distance from the pivot.
- 1.5.2.3Apply the principle of moments with one force on each side of the pivot, including balancing a beam.
- 1.5.2.4State that an object is in equilibrium when there is no resultant force and no resultant moment.
- 1.5.2.5Supplement: apply the principle of moments when there is more than one force on each side of the pivot.
- 1.5.2.6Supplement: describe an experiment showing that there is no resultant moment on an object in equilibrium.
