Answer:

Option A. Point A

Explanation:

Considering the diagram given above, we can see that point A is at the extreme from the fulcrum. So applying a pull or a push from point A will lift the sheep most easily when compared to point B and C. Point B or C will only be considered most when we are trying to balance the level.

It is most easy to lift sheep from point A because the downward force due to the load of sheep will be distributed along length of lever.

In the given diagram,

  • The sheep can be lifted most easily from point A because the distance is greater than the point B, C and D.
  • It is most difficult to lift sheep from point D because distance is minimum, so the downward force is not distributed.

Therefore, it is most easy to lift sheep from point A because the downward force due to the load of sheep will be distributed along length of lever.
