alleryA lever lifts a big load with a small effort when the effort arm is:
AEqual to the load arm
BBent at the fulcrum
CLonger than the load arm
DShorter than the load arm
Answer & Solution
Correct answer: C. Longer than the load arm
1. Mechanical advantage is effort arm over load arm.
2. A longer effort arm makes it greater than one.
3. Then a small effort lifts a large load.
