AOutput force divided by input force
BInput force divided by output force
COutput force multiplied by input force
DOutput force divided by input distance
Answer & Solution
Correct answer: A. Output force divided by input force
1. Mechanical advantage compares what the machine delivers with what the operator supplies.
2. It is the ratio of output to input force magnitudes, MA = Fo / Fi.
3. A value above one means the machine multiplies the applied force.
4. Inverting the ratio would make a force multiplying machine appear to have an advantage below one.
