how are defined F_v and F_e?

they are not defined :( just F_r and F_e (sorry that was messy too!!)

I think that : F_r is the resistive force F_e is the lifting force or similar

ohh ok!! :D

we have the greatest mechanical advantage, when F_r > F_e, namley I lift a great force, with minimum lifting force

ohh so would that be machine A? :/

  • Michele_Laino
correct!

yay! :) thanks!!

since we have this drawing: |dw:1433089171283:dw| If I apply the same force F_e, I lift the greatest force using machine A
