Large guns require more strength than small ones, as the powder occupying in each the same proportional space, the small shot moves in say...
Página 152 - From hence it appears that, whether the piece be loaded with a greater or less weight of bullet, the action of the powder is nearly the same, since all mathematicians know that, if bodies containing different quantities of matter are successively impelled through the same space by the same power, acting with a determined force at each point of that space, then the velocities given to those different bodies will be reciprocally on the subduplicate ratio of their quantities of matter.
