प्रश्न
Explain why the mechanical advantage of a class II of lever is always more than 1.
उत्तर
- With Class II levers, the load L is positioned somewhere between the effort E and the fulcrum F.
- The fulcrum F and the effort E are located at the two ends of the lever.
- As a result, the effort arm is always longer than the load arm, and the load and the effort are on the same side of the fulcrum but moving in different directions.
- Therefore, the mechanical advantage is always greater than 1.
