Question

Is a longer lever arm better?

Answer 1

Answer:

yes

Explanation:

The rotational displacement scales inversely with change in angle as the lever gets longer, so less force is needed. If you used a 100 foot pole to lift a heavy object, you might be able to move that pole easily, but it won't change the angle much
