Turning effect of forces
Core concepts and learning points for this section:
Syllabus Points
Core
- 1.5.2.1 Describe the moment of a force as a measure of its turning effect and give everyday examples
- 1.5.2.2 Define the moment of a force as moment = force × perpendicular distance from the pivot; recall and use this equation
- 1.5.2.3 Apply the principle of moments to situations with one force each side of the pivot, including balancing of a beam
- 1.5.2.4 State that, when there is no resultant force and no resultant moment, an object is in equilibrium
Supplement
- 1.5.2.5 Apply the principle of moments to other situations, including those with more than one force each side of the pivot
- 1.5.2.6 Describe an experiment to demonstrate that there is no resultant moment on an object in equilibrium
