Answer 2

${\huge{\mathbb{\blue{\overline{\underline{\red{\overbrace{\underbrace{\orange{ANSWER}}}}}}}}}}$

Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys. This can be applied to many physical situations with rigid bodies, and can be used to analyze the force advantage gained in using various tools.
