Answer:

Additional torque.

Explanation:

#tau=rFsintheta#
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.
