Answer

LoadEffort\dfrac{\text {Load}}{\text {Effort}}

Reason — The factor by which a machine multiplies the force applied (i.e. effort) is called the mechanical advantage of that machine and it is the ratio of the load to the effort. In other words,

Mechanical Advantage=LoadEffort\text {Mechanical Advantage}=\dfrac{\text {Load}}{\text {Effort}}
