Question:

an input force of 50 Newtons is applied through a distance of 10 meters to machine with mechanical advantage of 3. If the work output for the machine is 450 newton x meters and this work is applied through a distnace of 3 meters, what is the output force of the machine

Answers

The output of the machine is                                      (output work) =  (output force) x (distance)                                        450 N-m      =  (output force) x (3 meters)Divide each sideby  3 meters:                Output force = (450 N-m) / (3 m)                                                           =    150 newtons .With all the information given about the output work, we don't need to know anything about the input work, or even the fact that we're dealing with a machine. It's comforting, though, to look back and notice that the output work (450 N-m) is not more than the input work (500 N-m).  So everything is nice and hunky-dory.___________________________________Well, my goodness !I didn't even need to go through all of that.Given:-- The input force to the machine is 50 newtons.-- The mechanical advantage of the machine is 3 .That right there tells us that-- The output force of the machine is 150 newtons.We don't need any of the other given information.
