Since the moment of the weight momento gravante D attached at the point C is equal to the moment of a weight twice as large as D placed at the middle point AC, through which the weight of have agreed that the moment of the weights thus located, namely, twice D plus AC, bears to the moment of AC the same ratio which the length HA bears to CA and since AG is a mean proportional between these two lengths, it follows that the moment of twice D plus AC is to the moment of AC as the square of GA is to the square of CA. But the moment arising from the weight momento premente of the prism GA is to the moment of AC as the square of GA is to the square of CA; thence AG is the maximum length sought, that is, the length up to which the prism AC may be prolonged and still support itself, but beyond which it will break. Hitherto we have considered the moments and resistances of prisms and solid cylinders fixed at one end with a weight applied at the other end; three cases were discussed, namely, that in which the applied force was the only one acting, that in which the weight of the prism itself is also taken into consideration, and that in which the weight of the prism alone is taken into consideration. Let us now consider these same prisms and cylinders when supported at both ends or at a single point placed somewhere between the ends. In the first place, I remark that a cylinder carrying only its own weight and having the maximum length, beyond which it will break, will, when supported either in the middle or at both ends, have twice the the prism AC acts, it follows that the moment of the resistance of the prism AC located at A is equivalent to twice the weight D plus the weight of AC, both acting..., 275116, Anthologies, 62, Fiction, 1025612, Subjects, 266239, Books, 65, History, 271173, Africa, 12447484031, Americas, 271237, Ancient History & Civilisation, 271604, Arctic & Antarctica, 271248, Asia, 271319, Australasia & Pacific, 271480, Europe, 268021, Historical Biographies, 12447619031, Historical Study & Educational Resources, 271287, Middle East, 271411, Military History, 882492, Russia, 772162, Social & Cultural, 771718, World History, 1025612, Subjects, 266239, Books, 922068, Astronomy, 277887, Charts, 277894, Popular Astronomy, 277888, Star Gazing, 277904, Stars & Interstellar Matter, 278270, Telescopes & Equipment, 277906, Theoretical & Mathematical Astronomy, 277886, Astronomy & Cosmology, 57, Science & Nature, 1025612, Subjects, 266239, Books, 278267, Aeronautics & Aerospace, 278272, Aerospace & Aviation Technology, 278268, Astronautics, 278115, Engineering & Technology, 57, Science & Nature, 1025612, Subjects, 266239, Books, 772136, History of Science, 922508, History & Philosophy, 57, Science & Nature, 1025612, Subjects, 266239, Books, 922864, Applied Physics, 278409, Physics, 57, Science & Nature, 1025612, Subjects, 266239, Books, 922846, Mechanics, 278409, Physics, 57, Science & Nature, 1025612, Subjects, 266239, Books<

Galileo Galilei was a great scientist, and therefore not afraid of causing controversy, even if he had to pay a great price. His public advocacy of the Copernican over the Aristotelian system of the universe flew directly in the face of biblical authority and ecclesiastical tradition.

His public advocacy of the Copernican over the Aristotelian system of the universe flew directly in the face of biblical authority and ecclesiastical tradition. Condemned and placed under house arrest by the Inquisition, Galileo nonetheless devoted his last years to the completion of his Dialogues Concerning Two New Sciences, which deals with motion and the resistance of solids. The Two New Sciences, which Galileo called his most important work, may be regarded as the summary statement of a life devoted to scientific experimentation and free inquiry untrammeled by tradition and authority.
