प्रश्न
The diagram shows wheel O pivoted at point A. Three equal forces F1, F2 and F3 act at point B on the wheel.
- Which force will produce maximum moment about A?
- Give a reason for your answer in (a).
उत्तर
- About point A, force F1 would result in the maximum moment.
- F1 has the greatest distance between the point of application of force and A. As a result, the maximum moment of force would be produced.
