The last page of folio 2 talks about rounded balances and how they react to gravity. Leonardo writes that if a balance was suspended in its center of gravity, then it would not move or oscillate, regardless of position. He then goes on to say that if there are two weights of equal mass on the ends of this balance, then, when moved from its starting position, the balance will never return to the starting position. After this, he theorizes that a balance in this same situation will move if one of the weights is along a straighter line of descent as compared to the other weight. He then disproves his theory by showing the balance and weights as symmetrically equal, meaning there is no reason for the balance to move.
