Best ResponseYou've already chosen the best response.0they are not defined :( just F_r and F_e (sorry that was messy too!!)

Best ResponseYou've already chosen the best response.1I think that : F_r is the resistive force F_e is the lifting force or similar

Best ResponseYou've already chosen the best response.1we have the greatest mechanical advantage, when F_r > F_e, namley I lift a great force, with minimum lifting force

Best ResponseYou've already chosen the best response.0ohh so would that be machine A? :/

Best ResponseYou've already chosen the best response.1since we have this drawing: dw:1433089171283:dw If I apply the same force F_e, I lift the greatest force using machine A
