Question

question 19 - multiple choice

1. what does \de\ mean in the lever image shown below?

the distance between the fulcrum (pivot point) and the resistance force (the load) being moved or overcome by the lever.
the fixed point or axis around which the lever rotates or pivots.
this is the weight or load that the lever works against. it is the output force or the object being moved.
this is the force that is applied to the lever to move it and its load.
the distance from the fulcrum to the point where the input force (effort) is applied.

Explanation:

In lever - related physics concepts, $D_E$ represents the distance from the fulcrum to the point where the input force (effort) is applied. This is a standard notation in the study of levers.

Answer:

The distance from the fulcrum to the point where the input force (effort) is applied.
