Additional torque.

#### Explanation:

$\tau = r F \sin \theta$
where r is the length of the lever arm, $F$ is the force applied, and $\theta$ is the angle of the force to the lever arm.
Using this equation, one could get a larger torque by increasing r, the length of the lever arm, without increasing the force applied.
