The Merriam Webster dictionary definition of "mechanical advantage" is "the advantage gained by the use of a mechanism in transmitting force; specifically : the ratio of the force that performs the useful work of a machine to the force that is applied to the machine." Ultimately you are aiming for minimum effort exerted for maximum output. This is why simple machines were invented.
