Turning effect of forces

What the syllabus asks of you

• Describe the moment of a force as a measure of its turning effect and give everyday examples
• Define the moment of a force as moment = force × perpendicular distance from the pivot; recall and use this equation
• Apply the principle of moments to situations 5 Apply the principle of moments to other with one force each side of the pivot, including situations, including those with more than one balancing of a beam force each side of the pivot
• State that, when there is no resultant force and 6 Describe an experiment to demonstrate that no resultant moment, an object is in equilibrium there is no resultant moment on an object in equilibrium
