3. A man lifts various loads with the same lever. The distance of the applied force from the fulcrum is 2.00 m and the distance from the fulcrum to the load is 0.500 m. A graph of resistance force vs. effort force is shown. What is the mechanical advantage of the lever? What is the ideal mechanical advantage of the lever? What is the efficiency of the lever? Show your work

I just need help identifying the Fr and Fe

@TheDream  can you help

anonymous · Answer

ideal advantage = length force side/ length load side. So here you have 2m/.5m. Meters cancel so answer is 4

anonymous · Answer

For efficiency divide mass by force applied. Take your answer and divide 4 by the number. You should get a decimal multiply it by 100 to get percentage.

I get what  your saying, but the way i learned to slove for mechanical advantage is MA= fr/fe and for ideal it is IMA= de/ dr

anonymous · Answer

so  how would i apply that to this

anonymous · Answer

I think it is the same think I learned how to do it this way not sure of how to do it the other. It seems to just be different names for the same thing.
