Question

what happens when mechanical advantage will be unity

Answer 1

Answer:

Moving a load from one place to another requires a fixed amount of work. Work is defined as Force times distance moved. ... If we use no mechanical advantage the force is not reduced (A=1), so we call this a mechanical advantage of 1, or "unity gain".
