alleryStart learning →For a nail puller, the mechanical advantage is:
ALess than one always
BImpossible to define
CGreater than one
DExactly equal to one
Answer & Solution
Correct answer: C. Greater than one
1. Simple machines are judged by their mechanical advantage.
2. Simple machines are compared by calculating their mechanical advantage.
3. For the nail puller, the mechanical advantage is certainly greater than one.
4. That is why a small applied force removes a firmly held nail.
5. A value above one means output force exceeds input force.
