Del moto delle ballotte di bombarde e della qualità della tromba e coda di tale bombarda.

Se la ballotta messa per forza sarà di maggiore moto che quella che sarà messa con facilità, o no.

Se una bombarda gitta 100 libbre di ballotta, s'elli è meglio a mettere 2 ballotte di 50 libbre per una e fare la tromba stretta, oppure colla tromba larga trarre una sola ballotta di 100 libbre.

Se la bombarda po trarre 2 o 3 ballotte con facilità, dimando se è meglio a fare la ballotta lunga o no.

Se una bombarda gitta 100 libbre di peso un miglio, quanto gitterà ella 100 ballotte d'una libbra l'una in un sol tratto?

Se la bombarda è meglio a essere d'equal vacuo o no.

Se la bombarda è meglio stretta in bocca e larga da piè, o stretta da piè e larga in bocca.

I2 85 v.

Of the motion of the balls of bombards, and of the quality of the barrel and breech of such a bombard.

Whether the ball put in by force will have greater motion than one put in with ease, or not.

If a bombard throws a 100-pound ball, whether it is better to load two balls of 50 pounds each and make the barrel narrow, or with a wide barrel to fire a single ball of 100 pounds.

If the bombard can fire two or three balls with ease, I ask whether it is better to make the ball elongated or not.

If a bombard throws 100 pounds of weight one mile, how far will it throw 100 balls of one pound each in a single shot?

Whether the bombard is better having a uniform bore, or not.

Whether the bombard is better narrow at the muzzle and wide at the base, or narrow at the base and wide at the muzzle.

The Motion of Cannon Balls: One Heavy Ball or Many?

Questions on ball weight, bore uniformity, muzzle shape, and range of the bombard

Weapons & Fortification Physics & Mechanics

A continued list of artillery questions, all text and no diagram, on the motion of bombard balls and the form of barrel and breech. Leonardo weighs whether a ball loaded by force flies farther than one loaded easily, and whether it is better to fire two fifty-pound balls from a narrow barrel or one hundred-pound ball from a wide one. He asks how far a bombard that throws a hundred pounds one mile would throw a hundred one-pound balls in a single shot, and whether the bore should be uniform, wide at the muzzle, or wide at the base.

One 100-pound ball, or two of 50 pounds?

He asks whether it is better to load two fifty-pound balls into a narrow barrel or a single hundred-pound ball into a wide one, and, if two or three balls can be fired easily, whether the ball should be made elongated. He also questions whether a bore should be uniform, or narrow at the muzzle and wide at the base, or the reverse.

Range of one weight versus many small balls

He asks whether a ball driven in by force moves more than one loaded easily. A quantitative problem follows: if a bombard throws a hundred pounds one mile, how far will it throw a hundred balls of one pound each in a single shot?
