How is mechanical advantage calculated? A. by adding effort force by resistance force B. by multiplying effort force and resistance force C. by subtracting effort force and resistance force D. by dividing resistance force by effort force

I would think it would be..... Idk.. i thought it was calculated by input / output >.<

hmmmm well I believe I answered one of your earlier questions by output/input however in this case you can assume that the machine is multiplying the input force to equal the resistant force, allowing you to move the object with the less input force (somewhat a definition of a simple machine) Thus, the resistant force would equal the output force, and as I said before the output force/input force equals the Mechanical advantage so output force/input force=resistant force/input force, which is D hopefully this wasn't too confusing
