The distance of the effort from the fulcrum is called the ________.
Effort arm
A lever turns about a fixed pivot point called the fulcrum, and the effort and the load act at different distances from that pivot.
These distances are what give the lever its turning ability, so each has a specific name in mechanics.
The perpendicular distance from the fulcrum to the point where the effort is applied is called the effort arm.
The corresponding distance from the fulcrum to the load is the load arm, so the two must not be confused.
The mechanical advantage of the lever is the ratio of the effort arm to the load arm, so a longer effort arm lets a smaller effort raise a given load.
Load arm names the wrong distance here, while mechanical arm and lever length are not the standard terms for the distance from the fulcrum to the effort.
Hence, the answer is Effort arm.
