lever arm
Force amplification distance
The lever arm is the perpendicular distance from the axis of rotation to the line along which a force acts.
In physics, this distance determines how effectively a force produces rotation—a longer lever arm means greater torque from the same force.
She gripped the wrench at the end to maximize the lever arm.
The term appears in engineering and biomechanics wherever rotational forces matter.
