Which type of lever is for balance?

Balance around a pivot comes from equal torques: the effort times its distance from the fulcrum must equal the load times its distance. A lever class is defined by where the fulcrum sits relative to the effort and the load, not by a function like “balance.” You can achieve balance with any lever class by adjusting the forces and the lengths of the arms, so no single lever type is inherently for balance. That’s why none of the listed lever types is singled out as the one for balance.
