lever arms
Force-amplifying rigid bars
Lever arms are the perpendicular distances from a pivot point to where force is applied.
In physics, a longer lever arm means greater torque with the same force—the principle behind why a longer wrench loosens stubborn bolts more easily.
In anatomy, lever arms describe how muscles and bones work together mechanically: The bicep's lever arm determines how efficiently it can flex the elbow.
