Where should the fulcrum be located in this lever to get the greatest mechanical advantage?


Answer:C) at position I because the length of the effort arm should be greater than the length of the load arm 

Answer 2

C. When ever it comes to questions like these, I like to think of a seesaw with a huge amount of weight on one end. Which position would work best for that? With the effort arm being longer, you have more leverage so the load arm will move easier.
